What is the name of test that visualizes coronary arteries?

Coronary arteriography is a medical imaging technique used to visualize the coronary arteries, which supply oxygen-rich blood to the heart muscle. It is performed by injecting a contrast dye into the coronary arteries and then taking X-ray images. Coronary arteriography can be used to diagnose coronary artery disease, such as atherosclerosis, which is a narrowing of the arteries due to plaque buildup.
