Fig. 2From: Cerebral microvascular and microstructural integrity is regionally altered in patients with systemic lupus erythematosusCorrelation analyses of median IVIM parameter value in a brain region formed by the intersection of IVIM parameter change clusters for the cSLE group vs. healthy control group. a The intersection region shown in yellow. b Median flow parameter vs. VCA z-score. c Median flow parameter vs. PMS z-score. d Median parenchymal diffusion coefficient vs. PMS z-score. e Median blood volume fraction vs. SLEDAI score. f Median effective diffusion coefficient vs. SLEDAI score. MNI z coordinate of each slice in a is indicated, and neurological convention is used. For each plot b–f, the regression equation, r value, and p value are providedBack to article page
