Figure 1. Baseline TSPO-PET DVR and MRI Volumes in Patients With MS and Healthy Controls.

(A) Patients with MS had a higher DVR in the thalamus compared to healthy controls. (B) Patients with MS had a lower PF of the thalamus and caudate compared to healthy controls. The Wilcoxon rank-sum test was used. DVR = distribution volume ratio; HC = healthy control; MS = multiple sclerosis; PF = parenchymal fraction.
