An MRI (Magnetic Resonance Imaging) scanner generates a magnetic field from 5,000 to 20,000 gauss; whereas the MME magnetic field is only 5,000 gauss. The safety of induction of high strength magnetic fields was clearly established during toxicity studies performed for the FDA approval of MRI.

However, the strong magnetic fields used in MRI and MME do preclude their use by individuals with implanted medical devices such as heart pacemakers, aneurysm clips in the brain and inner ear (cochlear) implants. In addition, people with metal objects close to or imbedded in an important organ (such as the eye) may not be eligible for MME treatment. Each individual’s circumstances and history will be carefully and completely evaluated prior to acceptance as a research participant.
