Our study was the first application of whole-brain voxel-wise comparisons of IVIM-derived normalized Ds and f values to show physiological alterations in cognition and emotion-related brain of patients with asymptomatic carotid vulnerable plaque.
(a) Increased Ds values at left median cingulate and paracingulate gyrus (DCG.L), posterior cingulate gyrus (PCG.L) and left precuneus gyrus (PCUN.L) (cluster size = 156), left middle frontal gyrus (MFG.L), orbital middle frontal gyrus (ORBmid.L) and superior frontal gyrus (SFG.L) (cluster size = 165) (p <0.05, FWE correction). (b) Decreased Ds values at right middle temporal gyrus (MTG.R), inferior temporal gyrus (ITG.R)(cluster size = 116)(p <0.05, FWE correction). (c) Decreased f values at MTG.R,ITG.R(cluster size = 85) (p <0.05, FWE correction).
