A CT scan is a test that combines X-rays and computer technology to produce cross-sectional images (often called slices) of the body. Angiography is a test in which a special dye (properly referred to as contrast) is injected into the blood vessels through a catheter, making veins and arteries visible on an X-ray. When an angiography is used to diagnose an arterial condition, it is called an arteriogram.
