Effects of the MR-DTI Characteristics of the Trigeminal Ganglion Target on Radiofrequency Treatment in Patients with Trigeminal Neuralgia: A Retrospective Observational Clinical Study

Figure 2

Bar charts of the diffusivity metrics (FA, MD, RD, and AD) of the right CNV obtained from preoperative, postoperative, and follow-up MR-DTI. Images show the diffusivity metrics (FA, MD, RD, and AD) of the affected CNV on preoperative, postoperative, and follow-up MR-DTI according to the segmentation of the trigeminal nerve and their corresponding changes across these time points. The red line represents the TGT and SCS in the CNV segmentation. TGT: trigeminal ganglion target; SCS: significant change segment.
