Cerebral Angiography

Cerebral Angiography is a test that uses contrast dye and x-rays to see how blood is flowing through the brain.

Your doctor may order this test to find problems with the blood vessels in your brain, a brain tumor, look at arteries before brain surgery, or to find a blood clot after a stroke. This test may also be needed if you have signs or symptoms of abnormal blood vessels, aneurysm, narrowing arteries in brain, or vasculitis.

How to Prepare:

  • The radiologist will meet with you and discuss the test
  • Tell your doctor if you have allergies, a history of bleeding problems, and if you are pregnant
  • You will need to fast the day of the procedure

What to Expect:

  • You will need to remove all clothing and wear a hospital gown.  The nurse will place an IV line.
  • You will lie down on an x-ray table and receive a mild sedative to help you relax.
  • After your skin is numbed, a catheter or thin plastic tube will be inserted into your hip area to deliver the contrast dye to blood vessels.
  • The x-rays will detect if there are any problems with your blood flow.
  • After the procedure, the catheter will be removed.
  • Pressure and bandaging will be applied to the injection site.

After the Procedure:

  • You will be monitored for several hours as the puncture hole near the hip heals and the sedative wears off.
