Abstract
Myocardial bridges are common and often benign, but can cause hemodynamically significant obstruction of blood flow with stress. Dobutamine stress positron emission tomography/computed tomography (PET/CT) is a powerful tool for non-invasively assessing for ischemia. We present a case of using dobutamine stress PET/CT to determine the significance of a myocardial bridge.
