Preliminary evidence supports the safety of diffusion weighted tractography in postoperative patients with deep brain stimulation. Here we further test the feasibility in both DBS-on and DBS-off status. Both DBS ON and OFF diffusion weighted imaging are safe and the tractography results are significantly comparable. Furthermore, we found that the nigrostriatal pathway's deterministic tractography is feasible. Our results highlight that DBS ON DTI is particularly fitting for those patients who cannot control their disease symptoms without stimulation but need MRI.
