Regions showing ALFF differences of the patients after TIPS in paired comparison.

Positive sign in the peak t-score represents increase, and negative sign represents decrease. All P*The region in the posterior cingulate cortex survived the height but not the extent threshold. ΔVol: volume difference; ALFF = amplitude of low frequency fluctuation; TIPS = Transjugular intrahepatic portosystemic shunt; BA = Brodmann's area; SMA = supplementary motor area; DLPFC = dorsal lateral prefrontal cortex; MPFC = medial prefrontal cortex; ACC = anterior cingulate cortex; PCC = posterior cingulate cortex.
