Angiography (arteriography)
 |
| Angiogram |
X-ray examination of arteries and veins with a contrast medium to differentiate them from surrounding organs.
The contrast medium is introduced through a catheter to show the blood vessels and the structures they supply, including organs. Angiography of diseased leg, brain, or heart arteries is necessary before corrective surgery. See also angiocardiography.
