Alexander Gotschalk, M.D., former editor of the Yearbook of Nuclear Medicine for more than a decade; Seymor Levitt, M.D., a radiation oncologist and past president of the Radiological Society of North America; and John McAfee, M.D., a retired researcher whose work led to advances in blood cell labeling, have been named winners of the 2004 Gold Medal Award, the RSNA's highest honor.
A pioneer in radiology research, Gotschalk made the first dynamic camera studies of the kidneys. He served as director of the diagnostic radiology residency program at Yale University School of Medicine, and is currently a professor of diagnostic radiology at Michigan State University, according to the RSNA.
"Alex has made great contributions to radiology and nuclear medicine over a long career," said RSNA President Brian Lentle, M.D., in a press statement. His work as an investigator in a prospective study of pulmonary embolism diagnosis has "greatly helped in our understanding of the natural history and diagnosis of pulmonary embolism," Lentle said.
Levitt, president of the RSNA in 1999, has been a member since 1965. He is the former head and clinical chief of the department of therapeutic radiology and radiation oncology at the University of Minnesota, where he is a professor of therapeutic radiology and radiation oncology.
McAffee's work led to development of the first technetium-99m-labeled phosphate bone scanning agents as well as other radioactive agents to label blood cells and track their distribution in body organs, which, Lentle said "have become the most widely used procedures not only in nuclear medicine, but also in radiology as a whole."
The latest awards, presented annually since 1919 after a unanimous vote of the RSNA board of directors, were announced this week at the society's annual convention in Chicago.
