A computerized tomography (CT) coronary angiogram is an imaging test that looks at the arteries that supply blood to your heart. It might be used to diagnose the cause of chest pain or other symptoms.
A CT coronary angiogram relies on a powerful X-ray machine to produce images of your heart and its blood vessels. These tests are noninvasive and don't require recovery time. Coronary CT angiograms are increasingly an option for people with a variety of heart conditions.
A traditional (not CT-based) coronary angiogram requires that a flexible tube (catheter) be threaded through your groin or arm to your heart or coronary arteries. If you have known coronary artery disease, your doctor might recommend a traditional coronary angiogram because you can also receive treatment during that procedure.
