John Lewin MD

John Lewin, MD, FACR, FSBI, is Associate Professor and Division Chief of Breast Imaging in the Department of Radiology and Biomedical Imaging at the Yale School of Medicine. Dr. Lewin's career has included positions in both academic medicine and private practice and has encompassed clinical care, research and teaching in all aspects of breast imaging.  His research has focused on technology development and evaluation, particularly digital mammography and contrast-enhanced mammography.   Early in his career, while at the University of Colorado, using one of the first prototype devices, he conducted the first large clinical trial comparing digital mammography to film mammography for screening. In 1999 he began studying the use of intravenous contrast with digital mammography. This work led to the development and clinical demonstration of dual-energy contrast enhanced mammography (CEM). Dr. Lewin continues to study both the technical and clinical aspects of CEM.  One of his current focuses is on tumor ablation. He is the Principal Investigator for a multi-center trial on laser ablation of breast cancers.  Dr. Lewin is past-president of the Society of Breast Imaging
