Coronary Computed Tomography Angiography and Calcium Scoring.

Cardiovascular disease is the leading cause of death worldwide and describes many heart and vessel disorders. One of these disorders, coronary artery disease (CAD), occurs because of narrowed or blocked coronary arteries. Computed tomography (CT) is used to diagnose CAD because it displays coronary artery stenosis and calcified plaques in the coronary arteries.
