You simply inform the technician on the day of the scan. Usually you fill in a form before the procedure which asks these questions. The powerful magnets in the mri scanner can heat any metal implants so you must inform them, then the equipment is adjusted accordingly. I believe they lower the intensity of the magnetic field.
