Magnetic Resonance Imaging (MRI)

MRI involves a powerful but harmless magnetic field and radio waves (like the kind that transmit FM music). By looking for abnormalities in structure, the epilepsy team can determine whether there may be seizure producing areas in or adjacent to the regions of structural change.


  • You cannot have any metal in your body, including braces. You will be asked to complete a Safety Questionnaire prior to the MRI.
  • Allow 2 hours for the procedure.
  • You will hear a loud knocking noise while the scanner is in operation.

Pediatric patients that require sedation to assist in the performance of the scan cannot eat for 6 hours prior to the scan. They can only drink apple juice or water up to 2 hours prior to the scan.
