Magnetic Resonance Angiography
WHAT YOU NEED TO KNOW:
Magnetic resonance angiography (MRA) is a test that uses magnetic fields and radio waves to take pictures of your blood vessels. An MRA can be used to look for a blockage or narrowing of blood vessels. It can also be used to check blood flow through your heart. An MRA can help your healthcare provider diagnose or treat a medical condition. It does not use radiation.
Return to the emergency department if:
You have any signs of an allergic reaction to the contrast liquid, such as:
- Trouble breathing
- Dizziness or fainting
- Swelling of your mouth or face
- Nausea or vomiting
- Sudden decrease in urination
- A rash, itching, or swollen skin
Contact your healthcare provider if:
- You have pain or bleeding at the injection site.
- You have signs of an infection, such as redness or swelling, at the injection site.
- You have numbness or tingling in an arm or leg.
- You have an area of skin that is swollen, red, or thick.
- You have questions or concerns about your condition or care.
Drink liquids as directed:
Liquids will help flush the contrast liquid out of your body. Ask how much liquid to drink after your MRA, and which liquids to drink.
Follow up with your healthcare provider as directed:
Write down your questions so you remember to ask them during your visits.
