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.
