It is expected to provide important insights into the occurrence of MHE disease symptoms and the related biological mechanisms behind them. Meanwhile, our findings also suggested that an abnormal susceptibility values in certain brain areas identified using the QSM may be a potential biomarker to reflect the severity of cognitive impairment and to monitor its progression in cirrhotic patients with MHE.
