Fig. 1. ALFF maps show differences between pre-LT patients and HCs (p < 0.05, corrected by AlphaSim).

Diffused ALFF decreases in bilateral calcarine, IPL, LG, PCu, PoCG, MCC, and right SMA and increases in bilateral LTC, PHG, right Hip, and SFG are observed in pre-LT patients relative to controls. ALFF = amplitude of low-frequency fluctuation, HCs = healthy controls, Hip = hippocampus, IPL = inferior parietal lobule, LG = lingual gyrus, LT = liver transplantation, LTC = lateral temporal cortex, MCC = middle cingulate cortex, PCu = precuneus, PHG = parahippocampal gyrus, PoCG = postcentral gyrus, SFG = superior frontal gyrus, SMA = supplementary motor area
