MR guided implantation of deep brain stimulators is demonstrated in a series of pediatric dystonia patients. In contrast to conventional implantation methodologies, the MR guided approach does not require an awake, cooperative patient. Thus, it is much more suitable to pediatric applications. Bilateral DBS electrodes are implanted in six dystonia patients with a mean age of eleven years. Highly accurate targeting accuracy is achieved and clinical outcomes, as measured by a standardized dystonia rating scale, are comparable with the best reported results using traditional surgical implantation methods
