Localization of DBS-Electrodes in a 3D Atlas of the Basal Ganglia

Introduction: Deep Brain Stimulation (DBS) has been established as an invasive therapy of treatment of severve forms of movement disorders such as Parkinson’s Disease (PD). Most patients with PD are treated by DBS in the area of the subthalamic nucleus (STN). However, the exact location of the best target site is still under debate. Methods: In a consecutive patient series (Zurich University Hospital, 2009–2011) we compared preoperative MRI planning, intraoperative target adjustment and postoperative CT reconstruction. The localizations of the DBS electrodes were documented in a 3-dimensional atlas of the basal…
