CT Angiography

A computerized tomography (CT) coronary angiogram is an imaging test that looks at the arteries that supply blood to your heart. It might be done to diagnose the cause of chest pain or other symptoms.

A CT coronary angiogram uses a powerful X-ray machine to produce images of your heart and its blood vessels. The procedure is noninvasive and doesn't require recovery time. CT coronary angiograms are used to diagnose a variety of heart conditions.

A coronary CT angiogram is different from a standard coronary angiogram. In the traditional procedure (non-CT angiogram), a flexible tube (catheter) is threaded through your groin or arm to your heart or coronary arteries. If you have known coronary artery disease, your doctor might recommend the traditional approach because you can also receive treatment during the procedure.

Coronary angiography is a test used to find out how much narrowing there is in your arteries.

• Angiography is an imaging test that uses X-rays to view your body’s blood vessels.
• The X-rays provided by an angiography are called angiograms.
• This test is used to study narrow, blocked, enlarged, or malformed arteries or veins in many parts of your body, including your brain, heart, abdomen, and legs.
• A coronary angiogram is an X-ray of the arteries in the heart. This shows the extent and severity of any heart disease, and can help you to figure out how well your heart is working.
