In this work, we investigate the use of a sub-millimeter quantitative susceptibility mapping (QSM) protocol for preoperative imaging of the suthalamic nucleui (STN) for planning of deep brain stimulation (DBS). Image scoring revealed superior performance of QSM compared to the conventional T2 weighted (T2W) protocol. In contrast to T2W, image scores further increased for QSM when resolution was increased.
