[Coronary heart-CT].

Ischemic heart disease holds first place in WHO mortality statistics. Thanks to recent technical developments in computer tomography (CT), it is now possible to examine the heart, and the coronary arteries in particular, with sufficient temporal and spatial resolution. Native examination of the heart including identification of coronary calcification has an effect on the risk stratification of asymptomatic patients in addition to classification of conventional risk factors. Contrast-enhanced CT coronary angiography can identify and quantify stenoses and localize non-calcified plaques. Furthermore, it is possible to evaluate coronary artery anatomy, vessel grafts and, to a lesser degree, coronary stents.
