The ability of selected imaging techniques, such as computed tomography (CT), to detect and quantify coronary artery calcifications as a marker of the presence and severity of coronary atherosclerosis has created a growing clinical interest in these applications. This article discusses the clinical importance of coronary artery calcifications, reviews the potential indications for coronary artery calcium scoring and describes the different imaging and reporting methods with special emphasis on electron beam CT (EBCT) and multi-slice spiral CT (MSCT). In addition, the implications of coronary calcium measurements in patients suffering from chronic renal failure will be mentioned.
