OCD, obsessive–compulsive disorder; RD, radial diffusivity; CS, cluster size (i.e., number of voxels); PCR R, right posterior corona radiata; ACR L, left anterior corona radiate; SLF R, right superior longitudinal fasciculus; sCC, splenium of corpus callosum; gCC, genu of corpus callosum; bCC, body of corpus callosum.
White‐matter clusters with significantly increased RD (P TFCE < 0.05) in OCD vs. HC subjects. Coordinates indicate the location of the cluster peak in Montreal Neurological Institute (MNI) convention.
