computed tomography (ct) angiogram
a computed tomography angiogram (ct angiogram) is a test that uses x-rays to provide detailed pictures of the heart and the blood vessels that go to the heart, lung, brain, kidneys, head, neck, legs, and arms. the test uses a special dye that is put into a vein (i.v.) to make very detailed pictures of the blood vessels.
a ct angiogram can show whether a blood vessel is narrowed or blocked. the test can also show whether there is a bulge (aneurysm) or a buildup of fatty material called plaque in a blood vessel.
