Volumetric measurements of thalamus. A, Both MHE group and No-He group exhibited a higher average thalamic grey matter volume than healthy controls. The MHE group also had a higher average thalamic grey matter volume than No-HE group. B, Both MHE group and No-He group exhibited a lower thalamic volume estimated by FreeSurfer than healthy controls. C, Mean thalamic volume manually measured by a radiologist in three groups. D, When cirrhotic patients who ranked class B and class C in Child-Pugh score only were included, both MHE group and No-HE group had a larger thalamic volume than control group.
