What is a CT coronary angiography?

A CT coronary angiography (CTCA) is a medical imaging procedure that uses computed tomography (CT) technology to visualize the blood vessels of the heart, specifically the coronary arteries. The coronary arteries are responsible for supplying oxygen-rich blood to the heart muscle. CTCA is a non-invasive way to assess the presence of blockages or narrowing in these arteries, which can be indicative of coronary artery disease (CAD) or other heart conditions.
