Coronary Artery Calcium Scoring is used as a noninvasive screening test for coronary artery disease.
CT scanning of the chest is performed and special software is used to measure the amount and distribution of coronary arterial calcification. This “calcium score” is used to determine the risk of a future cardiovascular event.
The calcium score does not directly correlate with narrowing of a specific vessel, but correlates in a more general sense with the overall severity of atherosclerotic disease.
Cardiac CT Angiography and Coronary artery calcium scoring may be performed together.
