Data from Indiana University Advance Knowledge in Parkinson's Disease (Susceptibility-weighted Mri Approximates Intraoperative Microelectrode Recording During Deep Brain Stimulation of the Subthalamic Nucleus for Parkinson's Disease).

A recent study conducted at Indiana University explored the use of susceptibility-weighted imaging (SWI) in deep brain stimulation (DBS) for Parkinson's disease. The researchers compared the accuracy of SWI with intraoperative microelectrode recording (MER) in determining the borders of the subthalamic nucleus (STN), a target for DBS. They found that SWI accurately predicted the entry into the STN but underestimated its length and ventral boundary. The study suggests that further refinement of imaging protocols may improve the imaging of the ventral boundary of the STN. [Extracted from the article]
