Prof. Dr. Martin R. Prince is currently a Professor of Radiology at Cornell and Columbia Universities in New York City, focusing on clinical body MRI and MR angiography, developing new MR imaging techniques, and mentoring trainees. He received his medical degree from Harvard University and a doctoral degree in medical physics from the Massachusetts Institute of Technology. After completing an internal medicine internship at the University of California, San Francisco, he undertook an angiography research fellowship at Massachusetts General Hospital and then stayed on at MGH to complete a radiology residency and an MRI fellowship. He is known for developing contrast-enhanced MR angiography, for which he received the Gold Medal of the International Society of Magnetic Resonance in Medicine. In addition to MRA, he has pioneered MR imaging methods for pulmonary, liver, pancreatic, cardiac, placenta, kidney, and skin investigations, as well as in other organs. He has over 25 publications on autosomal dominant polycystic kidney disease exploring organ volume measurements for assessing disease course and response to water or tolvaptan therapy and correlations with pleural effusions, pericardial effusions, free pelvic fluid, cisterna chyla, liver cysts, pancreatic cysts, splenomegally, kidney stones, hemorrhagic cysts, IVC compression, and water therapy.
