[Abstract] Objective: To evaluate the accuracy of the application of MRI Argus assessment in liver volume before pediatric living donor liver transplantation (PLDLT).Materials and Methods: Eleven PLDLT donor livers underwent enhanced MRI scanning. Donor liver volumes were calculated with importing venous phase reconstruction data to Argus software, correlation analysis was used with actual removal of the liver weight during the operation.Results: Paired t-test showed there was statistically significant difference` (P<0.01) between liver volume measured by MR Argus software (357.00±72.37) ml and real liver weight in intraoperative actual removal (284.45±61.27) g. Person correlation test showed liver volume measured by MR Argus software had a significantly positive correlation with real liver weight (r=0.982, P<0.001). Graft weight could be expressed in the equation: W real liver weight (g) = 0.832 × V liver volume measured by MR Argus-12.46.Conclusion: MRI Argus software is helpful to estimate graft volume before surgery, utilizing the regression equation can accurately forecast the quality of liver transplantation, and providing assessment for preoperative graft volume.
