Coronary CT Angiogram

What is a Coronary CT Angiogram?

A Coronary CT Angiogram is a heart-imaging test to check for fatty deposits or calcium deposits that may have built up in the coronary arteries, which supply blood to the heart muscle. If left untreated, these areas of build-up, called plaques, can cause heart muscle disease. Heart muscle disease, in turn, can lead to fatigue, shortness of breath, chest pain and/or heart attack.

What happens during the test?

A Coronary CT Angiogram comes from a special type of X-ray examination. Before the scan you will receive an iodine-containing contrast dye as an IV solution to ensure the best images possible. The same IV in the arm may be used to give a medication to slow or stabilize the patient’s heart rate for better imaging results.

During the examination which usually takes about 10 minutes, X-rays pass through the body and are picked up by special detectors in the scanner. The information collected during the Coronary CT Angiogram examination is used to identify the coronary arteries and, if present, plaques in their walls with the creation of 3D images on a computer screen.

When will I get the results?

The results will be discussed with you at a scheduled appointment with your doctor.
