MR Angiogram is a newer form of MRI that is designed to look at arteries and veins. This test helps the radiologist view healthy and diseased blood vessels in the brain and neck.
MRI and MRA can be performed together for a more complete evaluation. MRA is less invasive than Catheter Angiography and can be done as an outpatient procedure. MRA can be performed with or without an IV contrast dye.
Your doctor may order an MRA to look for:
- Plaque in the arteries
- Blockage in blood flow
- Blood vessel malformation
- Causes of headache
How to Prepare:
- If you are claustrophobic, your doctor can ask for IV sedation during the MRI
- Notify the technician about any devices or metal objects inside your body
- Notify the technician of any allergies, and if you are pregnant or nursing
- If you receive a sedative, you will need someone to drive you home afterward
What to Expect:
- You will be asked to remove clothing and other objects
- If a contrast dye is needed, the technologist will place an IV
- A headset or earplugs will be provided to block noise from the scanner
- You will lie down on a table that slides you into the scanner
After the scan, you may be monitored for a period of time to make sure there aren’t any after effects from the contrast dye and to allow the sedative to wear off. The radiologist will send a report to your doctor.
