DTI maps show negative fractional anisotropy (FA) (A), and positive mean diffusivity (MD) (B) and radial diffusivity (RD) (C) correlations with Wisconsin Card Sorting Test (WCST) Errors in all cirrhotic patients.

<p>Results are shown with a Threshold-Free Cluster Enhancement method at p<0.05 corrected. Rows show selected coronal, sagital and axial maxima coordenate slices on a MNI152 brain template image (MNI coordinates). Red-yellow voxels are negatively correlated FA values (A), blue-lightblue voxels are positively correlated MD values (B) and brown-lightbrown are positively correlated RD values (C) with WCST Errors scores. FWE = Family Wise Error; SLF = superior longitudinal fasciculus; CST = corticospinal tract; ILF = inferior longitudinal fasciculus; IFO = inferior frontal-occipital; CC = corpus callosum; CG = cingulate gyrus; UF = uncinate fasciculus; HC = hippocampus.</p

DTI maps show reduced fractional anisotropy (FA) (A) and increased radial diffusivity (RD) (B) in patients with falls compared to those without falls, including Psychometric Hepatic Encephalopathy Score (PHES) as a covariate.

<p>Results are shown with a Threshold-Free Cluster Enhancement method at p<0.05 corrected. Rows show selected coronal, sagital and axial maxima coordenate slices on a MNI152 brain template image (MNI coordinates). Red voxels have significantly decreased FA values (A), and brown-lightbrown voxels have significantly increased RD values (B). FWE = Family Wise Error; SLF = superior longitudinal fasciculus; CST = corticospinal tract; ILF = inferior longitudinal fasciculus; IFO = inferior frontal-occipital; CC = corpus callosum; CG = cingulate gyrus.</p

DTI maps show reduced fractional anisotropy (FA) (A) and increased mean diffusivity (MD) (B) and radial diffusivity (RD) (C) in patients with falls compared to those without falls.

<p>Results are shown with a Threshold-Free Cluster Enhancement method at p<0.05 corrected. Rows show results of selected coronal, sagital and axial coordenate slices on a MNI152 brain template image (MNI coordinates). Green voxels represent the FMRIB58 white matter skeleton mask. Red voxels have significantly decreased FA values (A), blue voxels imply significantly increased MD (B) and lightbrown voxels represent increased RD values (C). FWE = Family Wise Error; SLF = superior longitudinal fasciculus; CST = corticospinal tract; ILF = inferior longitudinal fasciculus; IFO = inferior frontal-occipital; CC = corpus callosum; CG = cingulate gyrus.</p
