CT Coronary Angiogram vs Coronary Calcium Score Video
CT coronary angiogram (CTCA) and Coronary Artery Calcium (CAC) scoring are both non-invasive imaging tests that provide valuable information about the coronary arteries, but they serve different purposes and have some key differences. CTA is primarily used to evaluate the coronary arteries for the presence and extent of narrowing (stenosis) caused by plaque buildup (atherosclerosis). CAC assesses the amount of calcified plaque present in the coronary arteries. This information is used to determine the risk of a heart attack in future.
