What To Expect From Your Angiogram

A peripheral angiogram (also called an arteriogram) is a special kind of X-ray that allows your physician to see the blood flow through the arteries in your body.

  • The physician inserts a thin tube called a catheter into either your groin or your arm, guiding it to the blood vessel that needs to be examined.
  • Contrast (dye) will be injected, and X-rays will be taken of the blood vessel to detect areas of blockage.
  • The procedure takes about 60 minutes. Afterwards, there are several methods to close the catheter puncture site in the artery. Your physician will choose the method that is best for you.

You may be asked to remain on bed rest for up to 6 hours following the procedure, depending on the method chosen, and you will need to have someone drive you home.
See complete instructions on preparation for, and recovery from, the procedure.

Computed Tomography Angiogram (CTA)

A computed tomography angiogram (CTA) is a non-invasive imaging test that combines two technologies – the conventional CT scan and angiography – to create detailed images of the blood vessels.

As with an angiogram, you will receive contrast dye through a catheter to ensure the best images possible. Then X-rays will pass through the body and be picked up by 64 special detectors in the scanner. The images will be combined to create a 3D computer image of your blood vessels.
