Ideal placement of Deep brain stimulator (DBS) leads is within the Globus Pallidus Externus (GPe) and Globu Pallidus Internus (GPi). Currently, positioning is assessed intraoperatively by placing the lead into the region of Globus Pallidus (GP) and increasing the voltage. Facial twitching is observed for response to determine proximity to the internal capsule thereby indicating position within the GP.
The goal of my research project is to show that Diffusion Tensor Imaging with tractography can be used to map the ideal location for Deep Brain Stimulator lead placement for pre operative surgical planning. This will hopefully result in decreased operative times and improved clinical results for patients receiving Deep Brain Stimulators such as those with Parkinson's disease.
