White matter fractional anisotropy predicts Parkinson's disease medication changes with deep brain stimulation.
Diffusion-based tractography has been used to predict deep brain stimulation (DBS) outcomes in Parkinson's disease (PD), but the predictive value of fractional anisotropy (FA) maps, which can be generated with far less computation, remains underexplored. We retrospectively analyzed preoperative diffusion MRI from 143 p...
