Noninvasive assessment of coronary atherosclerosis by multidetector-row computed tomography

Abstract

Assessment of atherosclerotic plaque burden may help to further stratify asymptomatic subjects with an intermediate cardiac event risk according to their conventional risk factors. Coronary calcium screening is a simple and effective method to noninvasively assess the atherosclerotic plaque burden. Standardized quantification of the coronary calcium mass will allow the results of ongoing prospective cohort studies to be used for any computed tomography (CT) scanner, electron-beam CT, as well as multidetector-row CT. Coronary multidetector-row CT angiography may have the potential to visualize vulnerable plaques that are prone to rupture and cause acute coronary symptoms. However, neither the reliability of detection nor the strategies for intervention of vulnerable plaques with multidetector-row CT have to date been proven.
