Regions showing brain volume differences between MHE patients and healthy controls.

Positive sign in the peak T-score represents increase, and negative sign represents decrease in brain volume. All PGM = gray matter; WM = white matter; MHE = minimal hepatic encephalopathy; MNI = Montreal Neurological Institute; BA = Brodmann’s area; ACC = anterior cingulate cortex.峰值T评分中的正号代表脑体积增加，负号代表脑体积减少。本研究所用缩写对应关系如下：PGM代表灰质（gray matter），WM代表白质（white matter），MHE代表轻微肝性脑病（minimal hepatic encephalopathy），MNI代表蒙特利尔神经学研究所（Montreal Neurological Institute），BA代表布罗德曼分区（Brodmann’s area），ACC代表前扣带回皮层（anterior cingulate cortex）。
