Magnetic Resonance Imaging (MRI) Of The Breast: Risks
Content provided by Healthwise
Risks
There are no known harmful effects from the strong magnetic field used for MRI. But the magnet is very powerful. The magnet may affect pacemakers, implantable cardioverter-defibrillators (ICDs), artificial limbs, and other medical devices that contain iron.
If you may have metal fragments in your eyes, an MRI can cause damage to the retina. If there is a concern about metal fragments in the eye, most MRI clinics will do X-rays of the eyes before the MRI. If metal is found on the X-ray, the MRI will not be done.
Iron pigments in tattoos or tattooed eyeliner can cause skin or eye irritation problems.
There is a small risk of having an allergic reaction if contrast material is used during the MRI scan. Most reactions are mild and can be treated with medicine. There is also a small risk of infection at the IV site.
