Magnetic Resonance Angiogram (MRA)
How To Prepare
Before a magnetic resonance angiogram (MRA), tell your doctor and the MRI technologist if you:
- Are allergic to any medicines. The contrast material used for MRA does not contain iodine. If you know that you are allergic to the contrast material used for MRA, tell your doctor before having another test.
- Are or might be pregnant.
- Have any metal implanted in your body. This information helps your doctor know if the test is safe for you. Tell your doctor if you have:
- Heart and blood vessel devices such as a coronary artery stent, pacemaker, ICD (implantable cardioverter-defibrillator), or metal heart valve.
- Metal pins, clips, or metal parts in your body, including artificial limbs and dental work or braces.
- Any other implanted medical device, such as a medicine infusion pump.
- Cosmetic metal implants, such as in your ears.
- Have an Reference intrauterine device (IUD) Opens New Window in place. An IUD may prevent you from having the MRA test done.
- Become very nervous in small spaces. You need to lie very still inside the MRI machine, so you may need to have the test done with open MRI equipment. It is not as confining as standard MRI machines. You may need medicine to help you relax. Some blood vessels may not be seen clearly with an open MRI scanner.
- Have any other health conditions, such as kidney problems or Reference sickle cell anemia Opens New Window, that may prevent you from having an MRA using contrast material.
- Wear any medicine patches. The MRI may cause a burn at the patch site.
For some abdominal MRI tests, you may be asked to not eat or drink before the test.
You may need to arrange for someone to drive you home after the test, if you are given a medicine (Reference sedative Opens New Window) to help you relax.
If you are having blood flow studies, do not use tobacco products and do not eat or drink (including alcohol or caffeinated beverages) for 2 hours before the test. Do not take iron supplements on the day of the test.
You may need to sign a consent form that says you understand the risks of an abdominal MRI and agree to have the test done. Talk to your doctor about any concerns you have regarding the need for the test, its risks, how it will be done, or what the results will mean. To help you understand the importance of this test, fill out the medical test information form (What is a Reference PDF Opens New Window document?).
