MRIs, of the head or the body, may be considered if medically necessary, but the type of MRI machine may be restricted to a lower magnetic field (1.5 T), and certain types of MRI may require special equipment.  Always tell the radiology technician of any implanted devices. Typically, the DBS is turned off during the MRI and turned on afterwards. We work closely with you to coordinate pre- and post-MRI management.
