WebMagnetic resonance imaging (MRI) is a noninvasive test doctors use to diagnose medical conditions. MRI uses a powerful magnetic field, radiofrequency pulses, and a computer to produce detailed pictures of internal body structures. MRI does not use radiation (x-rays). Detailed MR images allow doctors to examine the body and detect disease. WebMagnetic Pulse Induction Method The neurons within the nerves and human brain are very sensitive to magnetic fields. The MPI method uses an induction coil to induce a low to medium magnetic field in and around the brain causing the …
