This test is used to check for heart disease in an early stage and to determine how severe it is. Coronary calcium scans are also called cardiac calcium scoring. The coronary arteries supply blood to the heart. Normally, the coronary arteries do not contain calcium. Calcium in the coronary arteries is a sign of coronary artery disease (CAD) .
