Ronald Peshock, M.D.

Ronald Peshock, M.D., is a Professor of Radiology at UT Southwestern Medical Center, with a secondary appointment as Professor of Internal Medicine. He serves as the Radiology Department's Vice Chair of Informatics and is a member of its Cardiothoraic Imaging Division. His clinical interests include atherosclerosis, cardiovascular disease, cardiovascular imaging, and coronary computed tomography (CT) angiography.

Dr. Peshock holds a bachelor’s degree in mathematics from Michigan State University in East Lansing. He earned his medical degree at UT Southwestern, where he also completed his residency in internal medicine and fellowships in cardiovascular diseases and cardiology research.

In addition to his expertise in biomedical imaging informatics, Dr. Peshock is also a primary reader of clinical cardiac magnetic resonance imaging (MRI) studies and CT angiography studies for UT Southwestern University Hospitals and Clinics and Parkland Hospital. 

Dr. Peshock’s research focuses on the development and use of MRI in the evaluation of cardiovascular disease and physiology. These studies begin with the development of basic MRI techniques for the evaluation of myocardial injury and ischemia. After validating these methods in animal models, he began to apply them to specific questions in the areas of myocardial function and blood flow, including the assessment of cerebral blood flow, alterations in skeletal muscle blood flow in an exercise setting, and understanding the fluid shifts in skeletal muscle that occur with exercise. 

As Imaging Director of the Dallas Heart Study, Dr. Peshock has mentored a series of researchers who have applied CT and imaging informatics to clinical investigation.

Dr. Peshock is an active member of multiple professional organizations, including the American College of Cardiology, the American Medical Informatics Association, the Society for Imaging Informatics in Medicine, the American Medical Association, the Texas Medical Association, and the Dallas County Medical Society. He also is on the Committee on Computational Medicine for the Institute for Computational Engineering and Sciences.

He has authored more than 150 peer-reviewed works and 25 additions to other texts and has served as a reviewer for numerous medical and scientific journals, including the Journal of the American Heart Association, Journal of the American College of Cardiology Cardiovascular Imaging, JAMA Neurology, Circulation Cardiovascular Imaging, BioMedical Research Journal, and Texas Heart Institute Journal.
