But just as with the issue of image disruption, donât assume that the presence of an electrical conductor inside your body is an automatic contraindication for an MRI exam. Consult your radiologist.

A: MRI means Magnetic Resonance Imaging-a safe scanning technique that produces images of your body without using ionizing radiation (x-rays). MRI scanners use a very strong magnetic field that is always active. During a scan, radio-waves are transmitted to align the hydrogen protons within your body.Tiny signals are given back from these protons. A computer converts the tiny signals into images used for diagnosis.RI scanners use a very strong magnetic field that is always active.
