Coronary calcium scan

A heart scan (coronary calcium scan) uses computerized tomography (CT) imaging to take pictures of the heart's arteries. It can detect calcium deposits in the coronary arteries. Calcium deposits can narrow the arteries and increase the risk of a heart attack. The image on the left shows where the heart is typically located in the body (A). The middle image shows the area of the coronary calcium scan image (B). The image on the right shows a coronary calcium scan (C).
