What is an MRI Angiogram Brain Scan?
An MRI Angiogram (MRA) Brain Scan is a non-invasive imaging test used to examine the blood vessels of the brain. It uses magnetic fields and radio waves to produce detailed images of arteries and veins without the need for surgery or X-rays. This scan helps doctors identify problems related to blood flow in the brain.
In some cases, a contrast dye may be used to enhance image clarity, as advised by the radiologist.
Why is an MRI Angiogram Brain Scan Done?
This scan is recommended to detect or evaluate:
-
Brain aneurysms
-
Narrowing or blockage of blood vessels
-
Stroke or risk of stroke
-
Arteriovenous malformations (AVM)
-
Blood vessel abnormalities
-
Causes of severe headaches, dizziness, or vision problems
