Abstract

Cardiac CT (CCT) has evolved rapidly over the past 20 years. Initially designed as a test for myocardial perfusion, CCT has developed into a potent screening test for atherosclerosis and a surrogate for invasive angiography (CT angiography). CT angiography, with high correlation to invasive angiography, is now being increasingly used in clinical practice as an alternative to cardiac catheterization or stress imaging. This technology’s high spatial temporal resolution allows for evaluation of major branches of coronary tree, compared to echocardiography, and nuclear or magnetic resonance imaging. The technology of CCT has undergone rapid transformation in recent years such that new scanners have sub-second image acquisition and multi-row capability (multi-detector CT). This article reviews the current scientific evidence and clinical uses for CCT.
