Professor of radiology

Expertise: PET, nuclear medicine, synthetic chemistry, oncology, imaging agents, radioisotopes, radionuclides

Bio: Welch, an expert in synthetic chemistry, has been a leader for more than 30 years in the development of synthetic imaging agents that have allowed doctors to use positron emission tomography (PET) to diagnose an increasingly wide variety of disorders. He is also head of the Radiochemistry Institute at the Mallinckrodt Institute of Radiology. Welch is the current principal investigator of Washington University's longest continuously renewed NIH grant, "Cyclotron Produced Isotopes in Biology and Medicine," now in its 45th year. The grant incarnation of the grant is dedicated to the development of new imaging agents that can help scientists better understand and diagnose the heart. The same grant supplied the funding that allowed WUSTL researcher Michel Ter-Pogossian to lead the development of the first PET scanner at the School of Medicine in the 1970s. Welch succeeded Ter-Pogossian as principal investigator in 1984.

Using a wide range of imaging techniques to visualize cancer in the body, radiology investigators at the Siteman Cancer Center at Barnes-Jewish Hospital and Washington University School of Medicine are expanding the boundaries of cancer detection, treatment and research. The strength of their efforts has received national recognition. For several years, Mallinckrodt Institute of Radiology at Washington University School of Medicine has ranked among the top three imaging programs in the United States in research grants received by the National Institutes of Health (NIH).
