Magnetic Resonance Angiography (MRA) of the head is a test that uses magnets and radio waves to create detailed images of the blood vessels in the head. A healthcare provider may order this MRA to check the blood vessels in the head for:

• Blood clots
• Blockages
• Other abnormalities or problems

MRA machines use powerful magnets, so tell your health care provider if you have any metal or medical devices in your body.

• Your healthcare provider may tell you not to eat or drink for at least four hours before the test.
• You must lie still during the exam, because moving could blur the images.
• If you are pregnant and your health care provider feels an MRI would give helpful information, he or she may order this test. Be sure to talk about the benefits and risks of the test with your health care provider.
• MRA can take up to an hour, but newer machines may be much faster.

The costs for this test include the charge for the test (facility charge) and physician charges (for performing or interpreting the test). You may get separate bills from the facility and the physician's office.

What should I ask my health care provider before having this test?

• Is there any special preparation for the test? (If so, get clear instructions on what you need to do.)
• What is my diagnosis and the reason for the test? Are the test results likely to change my treatment plan? If not, do I need the test?
• Are there any less expensive, but effective, alternatives to my getting this test?

Remind your health care provider if there are any metal(s) or medical device(s) in your body.
