Abstract

Objective: To explore the value of "one-stop" comprehensive MR evaluation in living donor of liver transplantation(LDLT). Methods: Sixty-one living liver donors underwent "one-stop" MRI before LDLT. All the primary data were reconstructed by maximum intensity projection(MIP) in post-procession workstation. The anatomy and variation of hepatic arterial, portal venous branching, hepatic veins and biliary system were evaluated and compared with the result of surgery. Results: Of the 61 the living donors, 48 had type Ⅰ, 7 type Ⅲ, 2 type Ⅷ and 1 type Ⅸ hepatic arterial anatomy according to Michel’s hepatic artery classification. Two had dominant artery to segment Ⅳ arising from the right hepatic artery(RHA) and 1 RHA from the celiac trunk(CT). Fifty-eight had conventional portal vein anatomy and 3 had “three bifurcation” type of portal vein. 41 had normal draining pattern of the hepatic veins. Left hepatic vein(LHV) and middle hepatic vein(MHV) formed a common trunk before draining into the inferior vena cava(IVC) were found in 18 cases. 2 inferior right hepatic vein(IRHV) were detected. Fifty-eight cases had normal anatomy of the hepatic duct, 2 had “three bifurcation” type bile duct, and 1 posterior right hepatic bile duct(RPHD) draining into the left hepatic duct(LHD). The diagnostic accuracy of MR in hepatic artery, portal vein, hepatic venous and biliary system was 96.7%, 100%, 95.1% and 93.4%, respectively. Conclusion: "One-stop" comprehensive MR evaluation can successfully delineate the anatomy and variations of hepatic vascular and biliary system and can be used in the preoperation evaluation of living donor in living donor liver transplatation.
