Cerebral Angiogram
Cerebral Angiogram
Cerebral angiography is a diagnostic test that uses an X-ray. It produces a cerebral angiogram, or an image that can help your doctor find blockages or other abnormalities in the blood vessels of your head and neck. Blockages or abnormalities can lead to a stroke or bleeding in the brain.
For this test, a doctor injects a contrast medium into your blood. The contrast material helps the X-ray create a clear picture of your blood vessels so that your doctor can identify any blockages or abnormalities.
Not everyone who may have arterial blockages needs to have cerebral angiography. It’s usually performed only if your doctor needs more information to plan your treatment after other testing. That’s because it’s invasive and carries some risks.
An angiogram can also be used to help treat some of the conditions involving the blood vessels of the neck and brain.
