CT is a radiographic test that uses X-rays to image the body in multiple “slices” which can be reconstructed in 3-dimensions using computers. Cardiac CTA uses an injection of intravenous contrast with subsequent CT imaging to outline the coronary arteries. These are the vessels which bring blood flow to the heart muscle and can become clogged leading to heart attack. This test can visualize plaque build-up and calcium in your coronary arteries and help your doctor plan how to best treat atherosclerosis.
What to Expect
The patient will go to the hospital and lie down on a table in the scanning device. This test can be performed as an outpatient and takes only about thirty minutes to complete.
