Angiography, also called Arteriography, is the X-ray imaging of blood vessels using a contrast agent (dye). The dye makes the blood vessels visible with an X-ray.
Its purpose is to show the blood supply moving to and from an organ. For example, an angiogram can show how blood flows to and from the kidney through the aorta and renal arteries.
Angiography is helpful to:
- Learn the location of a narrow or blocked blood vessel
- Treat a diseased blood vessel
- Find internal bleeding (to stop the bleeding)
- Locate and remove a blood clot in a blocked blood vessel
- Treat certain types of tumors by blocking their blood supply
- Make a map of your blood vessels before surgery
It is most commonly used to help with treatment, rather than for diagnosis alone.
