Advancing Pre-operative Targeting for Deep Brain Stimulation in the Globus Pallidus Internus: Functional Segmentation Based on Probabilistic Tractography

In the proposed pilot project, MRI data will be prospectively collected to show the feasibility of the segmentation algorithm and the potential relation to final lead positioning. Patients will be selected from those undergoing GPi DBS placement. This pilot data will serve as a basis for pursuing funding for a larger trial evaluating the prospective ability of the 3T targeting study to improve outcomes and decrease complications in GPi DBS placement. Improved outcomes and patient experience would be expected to further contribute to our facility as a center of excellence for treatment of movement disorders.
