Magnetic Resonance Angiogram (MRA)
What Affects the Test
Reasons you may not be able to have the test or why the results may not be helpful include:
- Pregnancy. Although the strong magnetic field used for an MRA does not appear to be harmful, MRA usually is not done when you are pregnant. If a view of your belly is needed and you are pregnant, an Reference ultrasound Opens New Window test may be done instead.
- You are using a medical device that contains metal, such as an Reference IUD Opens New Window, a pacemaker, some types of artificial limbs, or medicine infusion pumps. These devices can malfunction or cause problems during an MRA scan.
- Not being able to lie still during the test. The results of MRA may not be accurate if you can't remain still during the test.
- Being overweight and not fitting into the opening of some MRI scanners.
