Magnetic Resonance Angiogram (MRA): What Affects The Test
Content provided by Healthwise
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 ultrasound test may be done instead.
- You are using a medical device that contains metal, such as an IUD, 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 cannot remain still during the test.
- Being overweight and not fitting into the opening of some MRI scanners.
