Wm. Guy Weigold, MD, is medical director of the Cardiac Computed Tomography (CT) Service, MedStar Washington Hospital Center (MWHC), and director of the Cardiac CT Core Laboratory, MedStar Cardiovascular Research Network and MedStar Health Research Institute. Under his directorship, MWHC initiated one of the first programs to apply multi-slice cardiac CT in a busy clinical setting. In this role, he supervises the performance and interpretation of all cardiac CT examinations at MWHC and collaborates closely with the cardiac catheterization laboratory and cardiac surgery staff.
Dr. Weigold's laboratory is equipped with a 256-slice scanner and serves as a beta test site for new CT equipment and software applications. As an experienced principal investigator, Dr. Weigold is frequently invited to lecture at national and international conferences. He is a founding member of the Society of Cardiovascular Computed Tomography, and he is often asked to lend his expertise in reviewing manuscripts for journals, such as Cardiovascular Radiation Medicine and the Journal of the American College of Cardiology. Dr. Weigold also directs MWHC’s cardiac CT training program, Cardiac CT in the Nation's Capital.
Dr. Weigold received his medical degree from the University of Minnesota and completed his internship and residency in Internal Medicine at Northwestern University. He completed a fellowship in Cardiology at MWHC and has received advanced training in Cardiac CT.

Physiologic evaluation of ischemia using cardiac computed tomography
Dr. Weigold and colleagues studied the benefits, limitations and future directions of two imaging techniques used to detect coronary artery disease. This work has been published by the Journal of Cardiovascular Computed Tomography (2014;8:272-281).
