简要总结
How to accurately and safely evaluate regional liver function before hepatectomy remains an important unsolved problem in the surgical management of hepatocellular carcinoma (HCC). We plan to develop a non-invasive, functional 3D-MRE-based method for preoperative regional hepatic functional reserve assessment, and to evaluate its ability to predict surgical risk and postoperative liver failure in patients with HCC undergoing hepatectomy.

结局指标
主要结局
Incidence of Post-Hepatectomy Liver Failure (PHLF)
时间窗: Within 90 days after surgery
Post-hepatectomy liver failure will be defined and graded according to the International Study Group of Liver Surgery (ISGLS) criteria (Grade A/B/C), based on postoperative bilirubin and INR values.
次要结局
- Correlation between preoperative 3D-MRE regional stiffness parameters and future liver remnant function(Baseline (preoperative))
