Official title
A Prospective Study on Preoperative Regional Liver Function Assessment Using Three-Dimensional Magnetic Resonance Elastography for Predicting Surgical Risk and Postoperative Liver Failure in Patients Undergoing Hepatectomy for Primary or Metastatic Liver Cancer
Overview
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.
Interventions
- Device Three-Dimensional Magnetic Resonance Elastography
Patients scheduled for hepatectomy will undergo a preoperative three-dimensional magnetic resonance elastography (3D-MRE) examination in addition to standard-of-care evaluation. 3D-MRE will be used to quantify regional hepatic stiffness and viscoelastic parameters (including shear stiffness, storage modulus, loss modulus, and damping ratio) across different liver segments, with particular attention to the future liver remnant. These parameters will be analyzed for their association with postoper
Primary outcome measures
- Incidence of Post-Hepatectomy Liver Failure (PHLF) [Time frame: Within 90 days after surgery]
Secondary outcome measures (1)
- Correlation between preoperative 3D-MRE regional stiffness parameters and future liver remnant function [Time frame: Baseline (preoperative)]
Eligibility criteria
Inclusion criteria
