American neuroradiologist (1940-2024), a leader and visionary in his specialty, who contributed to the development of head and neck radiology in his country. He served as president of the American Society of Neuroradiology, the American Society of Head and Neck Imaging, and the American Roentgen Ray Society.

Born in Baghdad, Iraq, his mother Isa was Swiss, which justified multiple summer trips to this country for Tony and his two sisters. His father, Nasif, was an important businessman, which also motivated a large number of family trips to various European and American countries.

Initially educated, along with his two older sisters, at the Middle East University in Lebanon, in Beirut, at the age of 17 he moved to California to continue his education. There he completed his bachelor's degree at La Sierra University in Riverside, finishing his medical studies at Loma Linda University in 1967.

He later completed his residency in Radiology at the White Memorial Medical Center in Los Angeles and in 1972 a fellowship in Cardiovascular Radiology at the Loma Linda University Medical Center. Focused on the field of neuroradiology, he completed a fellowship at the University of California, Los Angeles, National Institute of Neurological Diseases and Stroke, complementing his training as a postdoctoral fellow in Otolaryngological Radiology at the A. de Rothschild Foundation in Paris in 1973.

In 1984, he returned to his alma mater, Loma Linda University School of Medicine, as Director of Neuroradiology, holding academic positions as Professor of Radiology and Otolaryngology.

In 1996, he moved to the University of California, Irvine (UCI), as Chair of Radiological Sciences. His leadership ability greatly influenced the rapid development of the Department, excelling not only in the professional field but also as an educator and mentor, directly contributing to the training of more than 100 residents and being a source of inspiration for several generations of neuroradiologists.

As a pioneer and great expert in clinical imaging of the brain, temporal bone, and spine, he was a highly sought-after speaker at the most recognized national and international forums. He wrote 6 textbooks on head and neck imaging and more than 150 articles in the most prestigious journals, contributing to more than 70 book chapters. He was part of the editorial board of 7 scientific journals in his specialty.

A founding member of the World Federation of Neuroradiological Societies, he significantly contributed to the American College of Radiology, the American Medical Association, and the Radiological Society of North America. Interested during his later years in vascular lesions, he actively collaborated with the Vascular Birthmark Foundation, providing his expertise in the diagnosis and treatment of this particularly traumatic pathology in pediatric age.

In 2017, he was awarded Alumnus of the Year by the Loma Linda University School of Medicine Alumni Association, and in 2023 he received the Iner Sheld Ritchie Presidential Award from the same association. For years, he served as an invited examiner in neuroradiology for the American Board of Radiology.

An enthusiast of travel and outdoor sports, especially skiing, he was also a great lover of social life. Beyond his professional achievements, he was a respected and beloved man, of pleasant character, always willing to share his wealth of knowledge and time very generously.

English radiologist (1912-1995), one of the great international figures in skeletal radiology, founder of the International Skeletal Society, and co-author with Harold Jacobson of the famous book: The Radiology of Skeletal Disorders.

Born in Glasgow, Scotland, his parents died during his childhood, and he was raised by his older sisters and brothers, one of whom, a doctor, encouraged him to pursue this profession. Educated at St. John's College, Cambridge, he studied medicine at St. Thomas's Hospital Medical School in London. He represented his country, Scotland, in rugby in 1935.

He graduated in 1938, but his hospital career was interrupted by the outbreak of World War II, in which he served in the campaigns of Sicily, Anzio, Salerno, and also in Normandy, reaching the rank of lieutenant colonel. His unit was responsible for the liberation of prisoners from the Sandbortel concentration camp, an experience that marked him for the rest of his life.

After the war, he completed his residency in radiology. His interest in orthopedic radiology began in 1948 during his time at Lord Mayor Treloar's Orthopedic Hospital in Alton. During this period, he also worked part-time at the Royal National Orthopedic Hospital under the guidance of two great specialists: Campbell Golding and Eddie Allen, who sparked his interest in creating a file of interesting cases in this discipline.

In 1954, he joined the American University Hospital in Beirut as an associate professor for two years, an experience he referred to as very beneficial for learning American work methodology and also the skeletal pathology specific to the Middle East. In 1956, he returned as a consulting radiologist to the Royal National Orthopedic Hospital.

An important event in his career was the lecture he gave on the effect of steroids on bone structure at the 8th Middle East Assembly in Beirut in 1958, which led him to obtain his doctorate from Cambridge in 1959 and an invitation to speak at the RSNA in Cincinnati in 1960. There, a meeting he had with Harold Jacobson fostered a close and long-lasting friendship and fruitful cooperation between them, leading to the publication of the book The Radiology of Skeletal Disorders and the founding of the International Skeletal Society.

After a working lunch to develop the book, Ronald Murray suggested the idea of forming a small club or society that would meet annually to discuss various aspects of skeletal radiology. This idea was accepted by Harold Jacobson and Jack Edeiken, organizing a preliminary meeting at the American Roentgen Ray Society congress held in Washington in October 1972. Ronald Murray and 16 American radiologists attended. The rest is history.

He was the first Vice President and served as the second President from 1976 to 1978. For over 10 years, he held the position of editor-in-chief of Skeletal Radiology. In later years, he decided to resign from all committees of the Society to make way for younger people, believing it was the right thing to do.

A prominent lecturer, he delivered the Robert Jones Lecture at the Royal College of Surgeons of England, the Cadwell Lecture at the American Roentgen Ray Society, and the Skinner Lecture at the Royal College of Radiologists, as well as multiple lectures in the United States, Europe, Africa, and the Far East. He contributed to the training of many residents and young radiologists from other hospitals who came to rotate through his department.

He was the Baker Travelling Professor in Australia in 1974 and President of the Radiology Section of the Royal Society of Medicine in 1978-79. The British Society of Skeletal Radiologists established the Ronald Murray Prize, awarded in his honor to the best junior radiologist of the year.

He is remembered as a kind, enthusiastic, and generous person, concerned about the careers of those around him. A great athlete in his youth, he was an excellent golfer.

American radiologist (1942-2024), one of the first to face gender discrimination in her profession, which she bravely confronted. Her life was marked by a continuous pursuit of excellence, both for herself and for her residents and colleagues.

Born in Chester, Pennsylvania, to a family with limited financial means, she had a happy childhood. She completed her primary education at Chester Public School and her university studies at the University of Pennsylvania, working in various research laboratories to finance her education, and later at Hahnemann Medical College, where she earned her degree in 1964. During this time, she also worked at Hahnemann Hospital as a means of support.

She completed her residency at New England Deaconess Hospital and Boston City Hospital. Upon finishing, she moved to Columbus, Ohio, finding employment in the Ohio State University Radiology Department. There, she had her first encounter with fee discrimination related to gender. She took her case to court, achieving parity in fees for the few female doctors employed at that time in the department.

She settled in Rhode Island, where she again experienced gender discrimination. She was rejected by a radiology chief who remarked that he would "never hire a female radiologist." Fortunately, she was recruited by the Ray Medical Group (later renamed Rhode Island Medical Imaging or "R.I.M.I."). The rest of her life would be spent in Pawtucket and Providence.

At a time when there were very few women leaders in the field of radiology, she was elected President of R.I.M.I., a position she held for 15 years, during which the group experienced remarkable growth and significant progress in the academic field. Under Barbara's leadership, R.I.M.I. became the first radiology group affiliated with Brown Medical School, becoming the largest and most prestigious radiology center in the region.

Barbara was the driving force behind the establishment of the Anne C. Pappas Center for Breast Imaging at Rhode Island Hospital in 1996. She enjoyed personally mentoring the excellent technicians at the Center, who describe her as "the person who put Rhode Island Hospital on the map, providing it with the best breast cancer screening programs, equipment, and staff" during her tenure as director of the Pappas Center. She led the field of healthcare for patients with breast pathology in Rhode Island and Southern New England for many years.

Dr. Schepps was a leader in everything she did, serving as president of the Rhode Island Medical Staff Association and a member of the Rhode Island Hospital Board of Directors. She was also president of the Rhode Island Medical Society. As a Clinical Professor of Diagnostic Imaging at the Warren Alpert School of Medicine (Brown University), she received the prestigious "Milton W. Hamolsky" award in 2004, recognizing her as the outstanding physician.

She was a Renaissance woman: an artist, sculptor, crochet expert, golf enthusiast, and lover of reading and opera. Generous with her time in a diverse range of philanthropic activities and charitable works. After retiring, she spent part of the year in Maui, Hawaii, where she contributed as a teacher at the graduate school.

Having started her life in humble circumstances, Barbara worked tirelessly to become a prominent medical professional. She helped a large number of patients and mentored a generation of young doctors and imaging technicians. Her story is one of a life always committed to achieving excellence. The world has lost a driving force.

American radiologist (1934-2024), a pioneer in interventional cardiovascular radiology, a leader who popularized his discipline, adapting it to modern times.

Born in the small town of Vinita, Oklahoma, his vocation was inspired by the doctor who treated him after he suffered an accident on his family's farm, helping him save two fingers on his injured hand when he was 4 years old.

He left his home state to attend high school at Texas Christian University in Fort Worth and pursued his medical studies at the University of Texas Medical Branch in Galveston. During his university years, he was awarded a research fellowship to be conducted during the summer at Brookhaven National Laboratory in Upton, Long Island, New York, which helped shape his research profile.

After his internship at Philadelphia General Hospital (1960-61), he completed his residency in radiology at Massachusetts General Hospital in Boston, later spending a year as a clinical fellow at the Armed Forces Institute of Pathology in Washington. He returned to Mass General and later to New England Deaconess, which merged with Beth Israel in 1969, rising to the position of department chief at Beth Israel Deaconess Medical Center in 1975, a position he held until 1997.

During the merger of these two hospitals, his leadership skills and tireless energy greatly contributed to achieving a solid integration of the institutions. He established a national training program in oncological research, as well as a fellowship in interventional treatments, body imaging, and nuclear medicine.

With an innovative mindset, even during his residency at Mass General, he developed a new method for performing lymphangiography. He later contributed to the creation of new approaches in the treatment of liver disease, developing protocols for the percutaneous treatment of liver tumors.

Between 1985 and 1991, thanks to several grants from the National Institutes of Health, he developed the principles of magnetic resonance spectroscopy for liver transplants. In 2006, he focused on the development of coronary angiography using computed tomography, thus becoming a pioneer in non-invasive imaging studies of the heart.

Dr. Clouse's career spans over half a century, with more than 235 published articles, particularly focusing on the introduction of new techniques in diagnosis and interventional procedures. Gifted with an excellent talent for identifying and recruiting young and brilliant radiologists and researchers, he mentored the development of young talents from all five continents.

Fellow of the Society of Interventional Radiology, the American College of Radiology, the American Heart Association, and the Society of Cardiac Computed Tomography, in 2017 he was appointed Chair of Harvard Medical School, establishing a chair in his name.

He served as president of the New England Roentgen Ray Society and held various leadership positions in the Radiological Society of North America.

American radiologist (1945-2022), who transformed the practice of thoracic radiology after 37 years in the Department of Radiology and Biomedical Imaging at the University of California San Francisco (UCSF). His book High-Resolution CT of the Lung is considered the definitive text on this subject.

A native of San Francisco, she grew up in Kentfield with her parents Wayne and Norma and her sister Judith. Initially enrolled at Stanford University, he graduated in medicine at the University of California San Francisco, where he also completed his residency in diagnostic radiology, was chief resident, and later a fellowship in thoracic imaging.

He served in the Air Force as a major (1976-78) stationed at Travis Air Force Base (Fairfield, California), after finishing his military service he joined the Radiology Department of UCSF as a doctor, holding the position of Chief of Thoracic Imaging between 1995 and 2006, an essential period in the promotion of the section that acquired national and international prestige.

The contribution of Dr. Richard "Rick" Webb to the field of thoracic radiology is inescapable, his initial work with high-resolution thoracic TC constitutes the foundations of the Moderna evaluation of diffuse lung disease. During his career he was the author or co-author of more than 200 manuscripts, 8 books with different reissues in multiple languages and no less than 100 book chapters. His textbook High-Resolution CT of the Lung, published in 1992, now in its sixth edition, is considered the most important book in this discipline.

Dr. Webb's legacy in the field of radiology includes the training and tutelage of many of the world leaders in thoracic radiology of current times, given his passion and inclination for teaching. He was known by students, residents and clinical colleagues of UCSF, who highlighted his immense knowledge, his diagnostic acuity and his endearing and sympathetic way of being. Always close and dialoguing, he knew how to highlight the key concepts, with an extremely entertaining and entertaining teaching style.

A renowned lecturer, he gave lectures in more than 35 countries, being a regular in all UCSF continuing education programs. In 2004 he was appointed Hideyo Minagi Professor of Radiology at San Francisco General Hospital.

Swiss radiologist (1929-1995), one of the most prestigious leaders of European radiology of his time. Director of the Department of Medical Radiology at the University of Zurich.

The son of a Protestant minister, he went to school in Zurich and did his medical studies at the university of that same city, carrying out his radiological training under the tutelage of the famous Hans-Rudolf Schinz. Between 1959 and 1961 he was in Lund, Sweden, the Mecca of angiography at that time, under the direction of Olle Olson.

Back in Switzerland he started his academic career at the University of Bern, where he soon reached the rank of Professor of Radiology and Head of the Department, succeeding Professor Zuppinger. In 1987 he was appointed Director of the Department of Medical Radiology at the University of Zurich, thereby inheriting the chair of his first teacher, Schinz, a position he held until 1994. In this time interval he built a solid Department, which he endowed with the latest technological advances, including magnetic resonance and PET.

With a strong character and a serious face, the first impression that the new residents got of him was somewhat frightening, even though after the initial dialogue his human and understanding personality made an appearance, normalizing the situation. Upright and honest, he always supported and guided his residents and deputies to the professional positions that best suited their abilities. Sometimes, due to his solid religious formation, as the son of a Protestant minister, he would let slip some Biblical quote during the sessions with the residents.

With a great vision for the future, endowed with a great ability to stimulate official governments to invest in the most cutting-edge radiological technology, he was also an expert negotiator in relations with the other medical disciplines, managing to convince his colleagues of the advantages of a spirit of collaboration, with common objectives, in the face of possible “battles” for one or another competence or technology. He was a self-confident man and therefore willing to share.

He turned the Radiology Department of the University of Zurich into one of the most prestigious in Europe and with his international experience maintained strong relationships with other North American and Asian radiological centers. Very fond of football, he compared his Department to a football team, emphasizing his desire, as its coach, to play a great role in the “World Championship”, rather than in the “National Leagues”.

A dominant figure in Swiss radiology at the time, he led the Medical Radiology Society of his country and the general secretariat of the International Congress of Radiology (ICR), from where he promoted the use of radiological equipment in third world countries. Author of countless articles and book chapters, he was considered a great teacher and a renowned lecturer, highly sought after in various forums and congresses.

He died on November 6, 1995, the irony is that the announcement of his death appeared in the newspapers exactly 100 years after the discovery of X-rays by Guillermo Conrado Roentgen. An honorary member of several international societies, he was to receive this appointment from the Radiological Society of North America on November 27, 1995, a few days after his death. His wife Charlotte, at the head of the family, collected the award.

American radiologist (1929-2022), one of the first interventionists, a great innovator and researcher in the field of medical imaging. He developed his activity for more than 50 years at the University of Pennsylvania.

A native of New York, from the Bronx, after studying for a bachelor's degree in his hometown, he completed his medical studies at the University of Utrecht (Netherlands) in 1957, completing his residency in radiology at the University of Pennsylvania. After working for a few years at Stanford University and at the Massachusetts General Hospital in Boston, he returned to Pennsylvania at the end of the sixties.

A very sociable character, he liked working with the patient more than being in the reporting room or in the darkroom. A visionary in terms of how medical imaging could improve surgical procedures, he developed new techniques for the study of blood vessels that made possible percutaneous interventional treatment of digestive hemorrhages, avoiding surgery. He was a founding member and first president of the Society for Cardiovascular and Interventional Radiology.

Chairman of the Department of Radiology between 1975 and 1996, he organized and developed in the eighties the first hospital magnetic resonance imaging program in the country, being a few years later founder and president of the Academy for Radiology and Biomedical Imaging Research. He wrote and contributed to the development of the legislation that made possible the establishment of the prestigious National Institute for Biomedical Imaging and Bioengineering at the National Institutes of Health.

Considered one of the most outstanding radiologists of her time, she spent 50 years researching, teaching, managing and caring for patients at Penn University. The epitome of an academic radiologist, he was named the Eugene P. Pendergrass Professor of Radiology in 1977 and in 2001 the University of Pennsylvania established the Stanley Baum Professorship of Radiology.

Editor of Academic Radiology for 17 years, he was the author of countless articles and several books, giving multiple lectures as a guest professor on different continents. Awarded the gold medal of the Radiological Society of North America, the American College of Radiology and the Academy for Radiology and Biomedical Imaging Research, he led several professional organizations, including Physicians for Social Responsibility and the Institute of Medicine, the current National Academy of Medicine.

He encouraged young radiologists to continuous innovation and improvement: ”Your demand will increase in relation to how you demonstrate to interns and surgeons that you are the ones who do your job best throughout the institution”.

Still a native New Yorker, he became a valuable civic booster, embracing Philadelphia's historical, natural and cultural heritage, working in the 1990s alongside other leaders in recruiting the best and brightest personalities to live, study and work in the city.

A music lover, gifted with great manual dexterity, he played the violin in his youth, attended Philadelphia Orchestra concerts and Eagles soccer games. He and his wife Jeanne liked to spend long moments contemplating the Japanese koi pond they had at their home in Chestnut Hill.

American radiologist (1949-2022) world pioneer in the prenatal use of ultrasound, who revolutionized the diagnosis of fetal anomalies, such as Down syndrome.

Dr. Benacerraf, a former professor of gynecology, obstetrics, reproductive biology and radiology at Harvard Medical School and Brigham and Women's Hospital in Boston, had to work hard academically to overcome the difficulties posed by her dyslexia.

His father, a Venezuelan-born immunologist, shared the 1980 Nobel Prize in Medicine for his research in the field of genetics. His mother Annette (Dreyfus) Benacerraf, a housewife, belonged to a prominent French-Jewish family that included the army captain at the center of the famous Dreyfus affair. Annette's uncle, Jacques Monod, also shared the Nobel Prize for Medicine in 1965.

The Benacerrafs' Manhattan home was a “French oasis” where dinners and gatherings of friends included famous classical music virtuosos and prominent scientists, such as Francis Crick, the English biologist who helped decipher the double helix structure of the ADN molecule.

Despite her less than stellar academic grades, she was accepted to Barnad College. In an effort to overcome her dyslexia she took Evelyn Wood's popular speed reading course twice, but failed to do so.

After graduating in 1971, she entered, not without the help of her father's influence, Columbia University College of Physicians and Surgeons, without her dyslexic problem hindering her medical studies. After a first attempt as a surgical intern in 1976 and considering that with imaging, for which she was particularly gifted, she was in her element (“Images speak to me, when I look at an image I can see the structure, I can see things that no one else is able to see”), she undertook her radiology residency at Massachusetts General Hospital and subsequently a fellowship in ultrasound, which at that time was a somewhat rudimentary discipline, after which she opened her own practice in 1982: Diagnostic Ultrasound Associates.

For 10 years he was the only medical professional in the entire Boston area dedicated to prenatal ultrasound. His most notable discovery was that thickening of a skin fold at the back of the fetal neck, the so-called nuchal fold, was associated with Down syndrome and other chromosomal abnormalities. His first articles in 1985 considering the potential of ultrasound as a less invasive method of fetal screening (at that time performed only in women over 35 years of age by amniocentesis) applicable to patients of any age were not well received.

In Dr. Benacerraf's words: “I was almost booed off the podium in the course of several national congresses, with articles discrediting my work and my person. I was crushed, but willing to continue, I was right”. Her determination was recognized: ultrasound scans, as well as the determination of the nuchal fold, are now a routine part of prenatal care.

It is also worth mentioning his discoveries on the development of fetal hearing. Subsequently he also devoted himself to gynecological imaging: endometriosis, pelvic pain and ovarian cancer.

During her forty-year professional career, she helped diagnose thousands of patients, published hundreds of articles and several books, contributing to the training of a legion of specialists. An extraordinary teacher, with great brilliance in her diagnoses, she is considered a pioneer in the use of ultrasound in the service of women's reproductive health, contributing to the safety and peace of mind of expectant mothers.

Polish-born radiologist (1921-2019), pioneer in the field of musculoskeletal radiology. He was the first honorary member of the European Society of Musculoskeletal Radiology (ESSR).

Originally from Goglau, Silesia, he studied in Berlin, Gdansk, Innsbruck and Vienna. In 1947 he joined the Department of Radiology at the University of Kiel, a German city on the Baltic coast, where he was Head of Department from 1951 to 1964, and subsequently became Medical Director of the Institute of Radiology at the Katharinenhospital in Stuttgart, where he remained until his retirement in 1986.

During all these years he was a pioneer and ambassador of musculoskeletal radiology. Founder of the German Society of Osteology and the Society for Biomedical Engineering, in 1974 he became a member of the International Skeletal Society (ISS) and was its president from 1984-1986.

Member of twelve other national and international societies, in 2015 he joined the newly founded German Society of Musculoskeletal Radiology (DGMSR). Chairman of several meetings and congresses, the most outstanding being “Radiology Today”, which he organized annually, during the 1980s in the city of Salzburg, Austria, together with his friends Martin W. Donner (Baltimore, USA) and Hellmuth Ellegast (Salzburg).

His scientific production is reflected in more than 300 articles, 15 books and countless conferences. The generations of radiologists of his time remember with affection and pleasure the inspiring and motivating style of his lectures, his inexhaustible knowledge and his interest in certain research topics, considered as minor, but always important according to his concept.

He was editor of “Skeletal Radiology”, “Der Radiologe” (The Radiologist, organ of expression of the German Radiological Society) and of important books, including the “Encyclopedia of Medical Radiology”, “Frontiers in European Radiology”, and “Research in Radiology: A Century in Review”. Many of these publications, which at the time contained in-depth information on various research topics, are still relevant today.

He was also one of the first radiologists to show interest and intuit the future of quantitative imaging, which was translated, it could not be otherwise knowing Professor Heuck, in the book: “Radiological Analysis of Bones”, in which he already anticipated the interest in going beyond the diagnosis of entities such as osteoporosis or osteomalacia, advocating its quantification to establish an adequate evolutionary prognosis.

His commitment to radiology was extraordinary. An honorary member of various medical societies, as well as numerous committees and leadership teams, during his career he received countless honors and awards, including the Founders Medal of the International Skeletal Society, the Albers-Schoenberg Medal of the German Society of Radiology, and the German Federal Cross of Merit.

English radiologist (October 14, 1922 - August 22, 2014) who transformed his discipline through the use of modern imaging techniques, author in 1986 of the famous book Diagnostic Radiology, which is still relevant today.

A native of Leeds, the son of a tailor, he completed his medical studies in this city in 1945, subsequently working for 6 years as a general practitioner before specializing in radiology. He completed his training in general radiology at Sheffield University, moving to London in 1957, to the London Hospital for Diseases of the Chest, where he completed his training in different areas of the specialty.

In 1959 he returned as a consultant to Sheffield, reaching the rank of professor of diagnostic radiology at Sheffield University in 1984, where he retired 3 years later, remaining emeritus.

During all these years he played an important role in transforming radiology from a limited discipline, based fundamentally on conventional radiology, into a vast and indispensable specialty, in which imaging techniques based on computer technology were indispensable, providing information that was unattainable with conventional techniques, and avoiding invasive procedures of greater aggressiveness.

Dr. Grainger, aware that the core of the old radiological techniques had been improved in terms of safety and efficacy, and of the usefulness of the new image-guided therapeutic techniques, quickly adapted to these changes, stimulating their introduction into clinical practice. His work focused primarily on the modernization of diagnostic techniques for cardiovascular diseases and a broad spectrum of neurological pathology.

Sensing that contrast media, now predominantly administered intravenously, could cause adverse cellular changes in the body's tissues and also in the kidneys, through which they were excreted, he conducted numerous clinical trials with the manufacturing pharmaceutical companies, in order to establish their safer use in clinical practice.

His vast clinical experience, together with his encyclopedic knowledge of anatomy, pathology and radiation principles, made him a recognized, multifaceted figure; he could speak with similar authority about a congenital heart defect, a strange reaction to a contrast medium, or a rare neurological disease.

In 1986, he edited with Dr. David Allison the book Diagnostic Radiology (sixth edition in 2014), an excellent work of 2,000 pages and 4,000 illustrations, which is still in use. Author of more than 100 scientific articles published in the most prestigious journals, for 5 years he was the editor of Clinical Radiology, the journal of the Royal College of Radiologists, of which he was also vice-president.

A visiting professor at 19 universities outside his home country, including Stanford and Yale, he was regarded as a great communicator and teacher.

A simple and kind man, always respectful of all his colleagues and students, devoted to his family: his wife Ruth and his sons David and Jonathan, he earned the appreciation and affection of all those around him.

American radiologist (January 23, 1930-February 1, 2022), pioneer of modern radiation oncology in the field of pediatrics and ocular tumors, author of the first book ever written on the radiotherapeutic treatment of ocular tumors.

A native of Brooklyn, New York, he always wanted to emulate his father as a physician. He graduated from New York University Medical School in 1955. A year earlier he married Malyne Barnett, who for the next 67 years would be the central axis and most important person in his life.

After completing his medical studies, he worked at Meadowbrook Hospital on Long Island during the end of the polio epidemic, then moved to Charity Hospital in New Orleans where he completed his training in the field of radiology.

During the Korean War, enrolled in the Air Forces, he was assigned to the 5040 th US Air Force Hospital at Ladd Air Base, in the territory of Alaska, for what he said was the northernmost radiologist located in the entire Western hemisphere.

After the military service he returned to New York to work at Montefiore Hospital, both in diagnostic and therapeutic radiology. In 1961 he moved to Stanford University Hospital in Palo Alto, California, where he completed his training in the nascent field of radiotherapy. In 1968 he returned to New York, organizing the Radiotherapy Department of the SUNY Upstate Medical Center in Syracuse, where he served as chairman until 1994.

During these years he carried out research sabbaticals at the Gustavo Roussy Institute (France), Stanford University School of Medicine, Hahnemann University School of Medicine and Loma Linda University Medical Center.

As a researcher he specialized in pediatric and eyeball tumors. He wrote the first treatise on radiotherapy treatment of eye tumors. A member of the editorial team of prestigious journals of the specialty, he cooperated with the various governmental medical bodies in the establishment of training programs for radiation therapy residents and protocols for doctors and technicians of this discipline.

He published more than 240 articles in the highest level journals, cooperating in the training of hundreds of residents and medical students. He treated thousands of patients.

When asked how he was able to work in such a depressing field as cancer treatment, Bob (as he was known to his family and friends) commented, “You have to understand, most of my patients get better. Those I can't cure, I can add a few significant years to their lives. I know the prognosis of 95% of my patients from the first moment I treat them, only a small percentage of patients surprise me, for better or worse. But, overall, I feel that I provide a great deal of hope”.

Usually when Bob returned home from his day's work, he would set down his briefcase and then “wrestle” on the floor with his four children before dinner. This habit continued until 1993, when he “wrestled” with his children and broke the couch in his daughter-in-law's house before Thanksgiving dinner.

He was very fond of opera, sailing (although he once fell overboard) and skiing.

Intelligent, hardworking and modest, he earned the love of his family and friends, the respect of his peers and colleagues, and the gratitude of his patients.

It is with deep sadness that we bid farewell to Dr. Jorge Bisteni Bustani (1952-2022) One of the great promoters of Latin American Radiology, always supporting education and the development of events of the highest level. He also managed the administration of the CIR efficiently and legally constituted it in 2007. Dr. Jorge Bisteni was known for always supporting the boards of directors and made the CIR grow for the benefit of its members, in an atmosphere of respect, camaraderie and friendship. There is no doubt that the community of the Interamerican College of Radiology, as well as Latin American Radiology, will miss him.

The Dr. Jorge Bisteni Bustani was born in Mexico City on November 3, 1952 and studied medicine at La Salle University, graduating on July 13, 1975. However, he dedicated his life to administrative work and particularly to the organization of medical congresses.

Endowed with a great teaching capacity, he was a professor of various subjects at the School of Medicine and the preparatory school of La Salle University from 1976 to 1990.

English physicist (January 14, 1927-February 25, 2021), who played a crucial role in the development of two of the most important medical technologies of the present era: magnetic resonance imaging and positron emission tomography, as well as in the evolution and progress of medical physics.

Born in Kingsthorpe, Northampton, England, he obtained his physics degree from University College Nottingham, then part of the University of London, completing his research project on the magnetic properties of uranium in 1947 under the tutelage of Professor Leslie Fleetwood Bates.

He worked as an "assistant physicist" at the Liverpool Radium Institute where he completed his training as a hospital physicist, later joining the Hammersmith Hospital and Post Graduate Medical School in 1953. Together with C. J. Peachy he developed in 1959 the first whole-body isotopic scanner in the United Kingdom, whose first diagnosis was that of a brain tumor.

In 1964 he published his theories on electron spin resonance and its possible applications for medical purposes in the prestigious journal Nature, although these initial observations were not taken into account for a long time. A year later, he became head of the Chair of Medical Physics at the University of Aberdeen, where in his first lecture he predicted the important role that positron emission tomography would play in the diagnosis of various medical pathologies.

Mallard brought to Scotland, through a nationally popular subscription, the first positron emission tomography device, which was located at the Woodend Hospital, which today has become the John Mallard PET Centre at the Aberdeen Royal Infirmary.

During the 70s Professor Mallard coordinated a team of specialists led by Dr. Jim Hutchinson developed a magnetic resonance scanner (0.04 Tesla) that was used for the study of laboratory animals. This same team developed the first whole-body resonance scanner, which was diagnosed by its first patient on April 26, 1980.

During the 80s, his team implemented the "spin warp imaging" technique that allowed the acquisition of three-dimensional images eliminating the artifacts produced by the patient's movement, and at the end of this same decade developed the color image, but they had to return to the grayscale image because radiologists were not used to handling color.

He retired from the University of Aberdeen in 1992 and remained very active, cooperating in the international development of medical physics and biomedical engineering. He was the Founding President of the International Union of Physical and Engineering Sciences in Medicine (IUPESM), as well as the President of the International Organization for Medical Physics (IOMP). From this position he carried out the first attempt to achieve the recognition of medical physics and biomedical engineering by the International Council of Scientific Unions.

In 1992 he was nominated Officer of the Order of the British Empire, the IUPESM awarded him its first “Fellowship for International Leadership”, and in 2016 the IOMP established the “John Mallard Award” that rewards the medical physicist who has developed a high-quality scientific innovation with application in clinical practice. The American Association of Physicians in Medicine awarded him the “Landau Memorial Plaque”.

He is considered as one of the scientists who has contributed the most to the establishment and development of medical physics as an academic discipline.

English radiologist (1900-1979), who described the lines A, B, C, named after him, in patients with varying degrees of heart failure and elevated venous pressure. He was part of the medical team that treated King George VI during his illness.

Born on October 27, 1900 in Dundalk, in the south of Ireland, he moved to Vienna, after finishing his studies, then the center of the relatively new science of radiology, in 1923. On his return, after passing the Cambridge exam, he began his successful career as a radiologist.

A founding member of the Faculty of Radiologist of Ireland in 1939, he served as a major during the World War, receiving the Roentgen Award of the British Institute of Radiology in 1944.

A tireless worker, author of numerous articles and editor of the Journal of the Faculty of Radiologists, he was also the author and editor of the Textbook of X-ray Diagnosis, in six volumes, which was considered for many years as the definitive textbook of this discipline. His most important contribution was undoubtedly the description of the lines that bear his name in patients with varying degrees of heart failure. This description marked a new frontier in the field of radiological research, and the “Kerley lines” became a legend.

Consultant radiologist at Westminster Hospital and the National Heart Hospital, endowed with a brilliant and original mind, especially willing to carry out the most accurate diagnoses of the rarest and most extraordinary entities, mainly in the field of thoracic radiology, his approach was more intuitive than deductive, but he always performed it in close cooperation with the pathologist.

He carried out his teaching activity more through the written word than the spoken word, with a natural talent that reached its maximum expression as editor of two journals and author of two books on radiology, the last of which Advances in Radiology is still read in an entertaining and interesting way.

He received recognitions from various parts of the world: gold medal from the Royal College of Radiologist in 1967, fellow of the American College of Radiology, the Australian College of Radiology and the Faculty of Radiologists of Ireland, he was an advisor to the English Ministry of Health, as well as a member of the team, led by Sir Clement Price Thomas, attended to King George VI.

A brilliant man, extremely intelligent and with a prodigious memory, he was an extraordinarily funny person, with a great sense of humor. A lover of social events, always with a smile on his lips, a travel enthusiast, a member of the Travelers Club, he was a great golfer, as well as a lover of hunting and fishing. He was a popular figure not only in the hospital, but also in the various clubs to which he belonged.

Of an affable character, endowed with a kind of vital force that transferred in the treatment to his many friends, his death in 1979 was considered as a great loss not only in the field of radiology but in that of British medicine in general.

American radiologist (1934-2022), pioneer and head of the Musculoskeletal Imaging Division at Columbia University, New York, for more than 20 years, a period in which it was not easy to be a woman in the field of radiology.

Graduated from the New York University School of Medicine in 1957, she completed her residency in radiology at Bellevue Hospital Center, joining the Department of Radiology at Columbia University Irving Medical Center in 1960, where she was a renowned professional for more than 50 years.

Through his internationally recognized achievements, some of them legendary, he contributed to the prestige that for years kept the Department of Radiology of Columbia University among the institutions with the highest academic level in the country. She was one of the most prolific authors in the field of skeletal radiology, with more than 250 articles, including the last one she published in 2012 on non-neoplastic lesions that simulate primary bone tumors, she contributed much of the knowledge that was available about her specialty at that time.

Teacher and mentor of many young radiologists, her dedication to the residents was total, her sessions at the foot of negatoscope were followed by a wide audience, regardless of whether she was dedicated to that plot or not. A great teacher, an extraordinary communicator, she had a great sense of humor, which she knew how to convey in her stimulating classes and conferences.

Founding member of the International Skeletal Society, gold medal of this institution, as well as of the American Roentgen Ray Society, president of the New York Roentgen Society between 1994 and 1995, she was a guest lecturer of many American scientific societies and of other countries, including Switzerland and Brazil.

She married Rubem Pochaczevsky, also a radiologist, who was her great love and support throughout her life.

Dr. Feldman's extraordinary career took place over a long period, when it was not easy to be a woman in the field of radiology. He had the strength and character necessary to maintain his activity and professional contributions even in the toughest moments when he did not have enough support. Even after his retirement he kept active his desires to continue learning and teaching.

In his article: "Musculoskeletal Radiology: then and now...", published in Radiology in 2000, he provides a series of reflections, already considered classic, on the changes that have taken place throughout his career, prophesying that new technologies will continue to develop, will become indispensable and increasingly in demand, but that it will be necessary to imbue these new images with the appropriate clinical sense and the appropriate interpretation by the specialist so that they contribute in a relevant way to the well-being of the patient and to the improvement of his quality of life.

As her colleagues in the Department comment, “We miss her when she retired, we mourn her passing, but above all we celebrate her entire life's journey”.

Swiss chemist (1933-2021) who won the Nobel Prize in Chemistry in 1991 for the development of techniques aimed at analyzing the chemical properties of atoms, contributing to the development of the foundations of magnetic resonance and its applications in science and medicine.

He was born in Winterthur, where his ancestors had lived for more than 500 years. His father was a professor of architecture at the Technological Institute of this city. When he was 13, he found a box with different chemical compounds that had belonged to an uncle, a metallurgical engineer: “I was immediately fascinated by the possibility of trying all kinds of reactions, causing explosions or making the air in our house unbreathable... I soon knew that I would become a chemist,“ he wrote in his Nobel acceptance speech.

He studied chemical engineering at the Federal Institute of Technology (ETH) in Zurich, the same university where Albert Einstein graduated 50 years earlier. After military service he received his doctor's degree in 1962. After five years in California he returned to the ETH Zurich in 1968 where he carried out his teaching and research career until 1998.

He dedicated himself to the field of nuclear magnetic resonance spectroscopy, combining elements of chemistry, physics and engineering; concentrating on the development and refinement of electronic equipment for the bombardment of atomic nuclei with radio frequency, using new mathematical methods for measuring the responses of different atoms and thus determining their chemical properties.

The field of magnetic resonance spectroscopy had already been intuited in the forties by Felix Bloch, a Swiss-born scientist working at Stanford University and Edward Purcell, an American researcher at Harvard. Both won the Nobel Prize in Physics in 1952.

When Dr. Ernst started his work a few years later, there seemed to be very few practical applications of magnetic resonance imaging beyond chemical analysis. During his stay in California, integrated in the company Varian Associates, trying to specify the field of resonance spectroscopy, he used short and intense radio frequency pulses to bombard atoms, using complex computer-assisted mathematical algorithms, Fourier transforms, which significantly improved the results of the analysis.

After his return to Zurich, he developed high-resolution techniques that allowed the three-dimensional analysis of proteins and other large molecules, which were essential to lead the appearance of magnetic resonance imaging. These discoveries alone earned him the Nobel Prize in Chemistry in 1991, the award of which he learned in the cockpit of the plane in which he was making a transatlantic flight.

Regarding his discoveries, Dr. Ernst felt more like an instrument designer than a scientist: “My goal was to develop something that could be passed down to posterity, to provide other people with the possibility of solving problems”.

He believed that beyond his field of specialization he had to have other interests. He was a cello virtuoso, with an encyclopedic knowledge of classical music; he was also a great scholar and collector of Tibetan art, he used resonance techniques to examine the painting of works of art, getting the Dalai Lama to give a lecture at the University of Zurich.

American radiologist (1917-2012), pioneer in the field of imaging of the musculoskeletal system, whose distinguished career as a professor of radiology was developed for almost six decades at Stanford University.

The third generation of a medical family, he was born in Altoona, Pennsylvania. His father was a urologist and his mother was the superintendent of music at the local school and a fashion chronicler. He completed his medical studies at Yale, graduating in 1943, as well as his specialization in radiology. A fan of the good life during his university years, he frequently traveled to New York to keep up with the latest news and shows at jazz clubs.

He served as an instructor at the Navy Radiology School at Fort Sam Houston, San Antonio, between 1946 and 1948, contributing to the training of future specialists, and as chief of radiology at the orthopedic center of the Army of Occupation in Bad Constadt, Germany.

In 1948 he was “signed” by his previous teacher at Yale, the legendary Henry Kaplan, who had just been appointed chairman of the young radiology department of Stanford University. Jones, along with other young radiologists cooperated in the expansion and relocation of the medical school from its initial location in San Francisco to its current location on the Stanford campus, which took place in 1959.

In 1952 he married Margaret (“Peggy”) Crusisus whose long career as a pediatrician ran parallel to that of her husband.

Intrigued by the radiology of the skeletal system, he contributed, among other research projects, to the evaluation of the effects of exercise on bone density, as well as to the understanding of the pathophysiology of “tennis elbow”. During his 58 years diagnosing and treating patients with bone and soft tissue tumors, he built up an archive of more than 2,000 cases, which have been digitized and are now available for students and residents in the future. As a forerunner of today's modern technologies, he even devoted himself to the x-ray filming of heartbeat recordings.

He was a fundamental component of the team that contributed to making the Radiology Department of Stanford University one of the most powerful and prestigious in the country. Considered as a great teacher, he won the Henry J. Kaiser Award for Excellence in Teaching granted by the Faculty of medicine on several occasions, contributing to the formation of a large number of residents scattered throughout the United States.

In the 1980s it was classic to see him arrive at the hospital on his bicycle, dressed in his tweed jacket and a stack of notes pinned to his tie. His colleagues and students were like a second family to him; with his wife Peggy, they organized parties to commemorate anniversaries, birthdays and special events; Thanksgiving celebrations usually included half a dozen or more students. Their Stanford home served as a rehearsal center for a Dixieland jazz band, in which he played drums. One of his fellow radiologists called him “the glue that held us all together”.

When he assumed emeritus status in 1985, after having acted as a tutor or mentor to almost 900 graduates, he did not lose his passion for radiology, for years his colleagues kept consulting him on the most complex cases of musculoskeletal radiology.

British engineer (1938-2020), pioneer in the development of computed tomography, who led the team that manufactured the first brain scanner and the first full-body scanner of the EMI brand.

Born in Farnham, he was educated at Saint Andrews Preparatory School, Pangbourne College and Battersea College of Technology. He graduated from the Pye Laboratories in Cambridge in 1961, his mission was to manage and monitor the surveillance cameras and control systems of nuclear power stations.

In Trawsfynydd, he discovered a sheep trapped in the reactor dome and had to chase it stuffed in his bulky protective suit until he managed to get it out of the building. In 1966 he went to work at the company General Precision Systems (later Redifon) in Aylesbury, in the field of flight simulation.

In 1972, he was employed as chief engineer of the X-ray Division of EMI Medical Systems, in order to manufacture the computed tomography device designed by Sir Godfrey Hounsfield that had won him the Nobel Prize. Anthony's team added numerous improvements over the initial design, including the patient table, which is still used in Moderna scanners.

The initial test of the full-body scanner, based on Hounsfield's ideas, was carried out by Anthony and a group of colleagues in November 1973. Tony Williams of EMI Central Research Labs was the first to be scanned, while David King of Anthony's team controlled the device. After this initial success, the series production of the prototype began in 1974, in which Anthony and his Operating Division played an important role.

In 1975, as Manager of New Technology, Anthony led the development of the new CT-5000 scanner, designed to provide a higher speed of image acquisition. Later designs such as the CT-6000 and the CT-7070 helped to reduce acquisition times and improve image quality.

During this period EMI won the Queen's Awards for Innovation (1975) and Anthony published numerous articles on the development and evolution of computed tomography, being a participant of the team that presented the Faraday Lecture, with a title as suggestive as: "The electron that diagnoses”

In 1980 Philips Medical Systems contacted him to lead the development of its computed tomography technology, and in 1981 Anthony's team carried out a joint project with Sir Godfrey Hounsfield's team that crystallized in the T-500 (Sirius), a device that used a Moderna X-ray tube and a corona of detectors, obtaining the images much faster and with much lower energy consumption. In 1988 this prototype was obtaining 3D images, with a quality much higher than any other fourth generation device, being 20% cheaper.

The first model of the T-500 was installed at the Academic Hospital in Utrecht, performing its first spiral volumetric scan in April 1988. Anthony was convinced that the spiral scanner would become an essential diagnostic technology, although Philips was hesitant to introduce the design into the highly competitive computed tomography market.

Back in the UK he spent his last years teaching advanced electrical engineering courses at Oxford Brooks University.

Anthony was an example of those few individuals who know how to both lead and manage. He always saw in the figure of Sir Godfrey Hounsfield an innovator and did not hesitate to support him, even if his ideas, at first, were misunderstood or misinterpreted.

He was a lover of classical music and the study of the history of science and scientific instruments. He liked to explore the British countryside, usually in the late afternoon, so he could look at the stars.

Miguel Stoopen has left us and Mexican, Latin American, Hispanic and global radiology mourn his loss. A Mexican radiologist (1938-2021), Miguel was considered one of the best in his country and one of the most representative in all of Latin America. Miguel was a clear architect of the development and current relevance not only of the Mexican Society of Radiology and Imaging (SMRI) but also of the Inter-American College of Radiology (CIR), the organization that has contributed the most to strengthen and strengthen the ties of union and friendship between Latin American radiology with the Spanish and North American, including the United States and Canada.

A native of Mexico City, he studied at the Faculty of Medicine of the National Autonomous University of Mexico (UNAM), graduating in 1961 and subsequently completing the residencies of Internal Medicine, Gastroenterology and Radiology at the General Hospital of the National Medical Center of the Mexican Institute of Social Security. He completed his training with the sub-specialization in abdominal radiology in Paris, at the Saint Antoine Hospital, under the tutelage of Professor Edouard Cheerigié.

Back in his country, after brilliant oppositions, he became Head of Radiology at the Specialty Hospital of the La Raza Medical Center, and since 1993 he has been the medical director of the C.T. Scanner Group. In 2000 Miguel was also appointed Director of the Imaging Department of the Lomas Altas Clinic, of which he was executive vice president between 2009 and 2013.

Endowed with a great teaching and research capacity, he gave more than 1300 lectures in different Latin American and European countries, being the author of more than 300 scientific articles and 14 book chapters. He was editor of the Mexican Journal of Radiology between 1981-2000 and founding editor of this NOTI CIR, monthly electronic newsletter of the CIR. He was also the promoter and editor of the Advances in Diagnostic Imaging textbook series, a collection of 17 monographs by CIR authors, with a great work of disseminating radiological advances in Spanish-speaking radiology.

He was a distinguished member of multiple medical societies, including the Radiological Society of North America (RSNA), the American Roentgen Ray Society (ARRS), the International Society of Radiology (ISR), the American Institute of Ultrasound in Medicine and the Societé Française de Radiologie (SFR). Miguel, with great organizational talent, was the founder and served as Secretary of the Mexican Association of Hepatology, President of the Mexican Federation of Radiology and Imaging and President of the CIR (2006). Miguel received recognition from the world's most prestigious radiological societies, serving as Vice President of the RSNA and a Member of the ISR Board.

In possession of the Gold Medal of the Mexican Federation of Radiology and Imaging and the CIR, as well as the Mexican Society of Radiology, he was also chosen as an Honorary Member of the Argentine, Honduran, Ecuadorian and Spanish Societies of Radiology.

Miguel had such an impact on Mexican and Latin American radiology that his history could not be written without a chapter dedicated to the many educational, scientific and organizational achievements of Dr. Stoopen. Miguel was a man with global projection, proud to be a Mexican radiologist but culturally adept and integrated with French and North American radiology as well as Latin American. With a keen nose for looking for fruitful and lasting alliances, his efforts resulted in collaboration agreements with the SFR, the SERAM and the RSNA that provided professors and articles for CIR and SMRI events. It is noteworthy his work for decades as Scientific Director of the SMRI International Course traditionally held in February in Mexico City. This course became under his scientific tutelage one of the most successful annual educational events of assistance and impact in Latin America with the participation of the first swords of world radiology and the official co-sponsorship of the RSNA, the SFR, and the SERAM.

A man of affable character, of great culture and a lover of history, he was always close and in dialogue with everyone. Extraordinarily loved and respected by his classmates and students, he developed an important leadership role, not only in Mexican radiology, but in the whole of Latin American radiology, contributing greatly to strengthen the bonds of union and friendship with Spanish radiology, receiving months before his death the deserved appointment of Honorary Member of the SERAM.

A devotee and lover of the family, he coordinated perfectly with his wife Veronica, forming an endearing couple easy to identify in most conferences, which they attended together.
