Cardiac computed tomographic evaluation of coronary artery calcification: A review

Vascular calcification is most commonly due to atherosclerosis. It has been well documented that absence of coronary calcification on a chest CT (CCT) is associated with low cardiovascular events and good prognosis. High CT calcium scores often result in a higher incidence of cardiovascular events and worse survival. In asymptomatic patients with an intermediate risk for coronary artery disease, numerous studies have shown Coronary Calcium Scoring (CCS) has prognostic relevance and incremental prognostic value over conventional risk stratification. CT detected calcium score plays important role in patient management. This article will review various CT based coronary artery calcium scoring methods.
