Abstract

Recent advances in multidetector computed tomography (CT), with submillimeter spatial resolution, improved temporal resolution, and electrocardiographic gating, make it possible to image and accurately characterize the coronary arteries. Cardiac CT offers the ability to noninvasively assess cardiovascular anatomy, including coronary arteries, bypass grafts and stents, myocardium, pericardium, and cardiac function. A growing body of literature supports the prognostic value of coronary CT angiography. This article provides an overview of clinical applications, scanning protocols, limitations, and future developments of cardiac CT.
