Is a magnetic resonance angiogram (MRA) safe?

If you have a pacemaker, defibrillator, prosthetic joint, certain types of stents, surgical clips, mechanical heart valve or other metallic devices in your body, you might not be eligible to undergo a magnetic resonance angiogram (MRA). Whether you are depends on the type of metallic device. If you have tattooed eyeliner, let your physician know before the test, as tattoos contain metal that can be pulled by the magnetic field, which poses a risk that close to your eyes. Your doctor can tell you if an MRA is safe for you.

MRA is considered safe. However, people have been harmed if metal is in their body or in the room. Be sure to tell your physician if you have metal implants, and remove all metal from your body before the test. In addition, you cannot have a "dye" injection for the MRA if you have a known allergy to MRI contrast (gadolinium). The contrast dye used in MRA does not present a problem for people with an iodine allergy. If you have kidney problems, talk with your doctor.
