Abstract: Objective To determine the value of MR cholangiography(MRC)in the preoperative evaluation of biliary anatomy of living liver donors.Methods Fifty eight consecutive donors underwent MRC examinations and living liver transplantation.MRC was performed on a 1.5 T scanner with breath-hold rapid acquisition of T_2WI slab and breathing-gating 3D FSE T_2WI.Images of MRC and IOC were compared and classified according to the modified Huang's classification.Results Thity four(58.6%)liver donors showed normal biliary anatomy on IOC,and 24(41.4%)donors revealed variant bile anatomy.MRC correctly depicted biliary anatomy in 91.4%(53/58)donors.The sensitivity,specificity,positive predictive value and negative predictive value of MRC in distinguishing normal and difierent types of variant biliary anatomy were 83.3%(20/24),100%(34/34),100%(20/20),89.5%(34/38)respectively.Conclusion MRC can accurately assess the biliary anatomy in living liver donors and may guide the preoperative planning of liver transplant.
