ABSTRACT
Objective To study the regional homogeneity (ReHo) of default-mode network (DMN) in patients with minimal hepatic encephalopathy (MHE) with resting state fMRI.Methods Eighteen MHE patients and eighteen healthy controls (HC) underwent standard resting state fMRI scan.The resting state fMRI data were analyzed with the ReHo method to observe the changes of DMN in the patients in contrast to the controls.Results Compared to healthy controls,MHE patients showed lower ReHo in bilateral MPFC/anterior cingulate cortex(V=13.257 cm3;MNI coordinates=3,24,66;t=-3.493 7),bilateral precuneus/posterior cingulate cortex(V=4.752 cm3;MNI coordinates=9,-54,45;t=-2.634 1),while higher ReHe in right medial prefrontal cortex(V=5.049 cm3;MNI coordinates=21,63,6;t=4.017 5).Conclusion In MHE patients,there is abnormal neuron activation in the widespread DMN regions under resting state, which indicated abnormal spontaneous activity consistency within DMN and endogenous brain function injury in MHE patients.ReHo can be used to observe DMN changes in MHE patients.
