The goal of this study was to discuss the guidelines that permit patients with implanted deep brain stimulation
(DBS) system to undergo Magnetic Resonance imaging (MRI) safely. We reported our experience of 226 MRI performed
on 161 patients (134 dystono-dyskinetic syndromes and 27 Parkinson’s disease) of which 32 reimplantations.
The stereotactic protocol used for the anatomical target localization in our center involves a pre- and postoperative MRI
under general anaesthesia. The postoperative MRI allows measuring the possible error, checking the electrode position
and the absence of surgical complication. No complications, no haemorrhages, no electrode displacement or fracture, no
images similar to pallidotomy, and no neurological deficit were found related to MRI. We recorded only two minor hardware
related complications occurring after MRI: (1) a stimulator damage after spinal MRI and (2) a parameter reset after
Clinical data confirm MRI feasibility in patients with implanted deep brain stimulation system.
