Coronary CT Angiography

Coronary computed tomography angiography (CCTA) is a heart imaging test that creates three-dimensional images of the coronary arteries to help determine the exact location and extent of plaque buildup, which causes narrowing of the coronary arteries (the blood vessels that supply the heart). Patients undergoing a CCTA scan receive an iodine-containing contrast material as an intravenous (IV) injection to ensure the best possible images of the heart blood vessels. This new test is an excellent, less invasive and less expensive alternative to cardiac catheterization procedures. It is often used for patients who have coronary stents or bypass grafts to verify that the arteries are still open and functioning properly.
