BACKGROUND: The precise preoperative calculation of functional liver volumes for both donor and recipient is a crucial part of the evaluation process in adult living donor liver transplantation. The purpose of this study was to describe and validate our modus 3-D CT volumetry. PATIENTS AND METHODS: Native (unenhanced), arterial, and venous phase CT images from 62 consecutive live liver donors were subjected to 3-D CT liver volume calculations and virtual 3-D liver partitioning. Graft-volume estimates based on our modus 3-D volumetry, which subtracted intrahepatic vascular volume from the "smallest" (native) unenhanced CT phase, were subsequently compared to the intraoperative graft-weights obtained in all 62 cases. Calculated (preoperative) liver-volume-body-weight-ratios and measured (intraoperative) liver-weight-body-weight-ratios of liver grafts were analyzed. RESULTS: Preoperative calculations of graft-volume according to our modus 3-D CT volumetry did not yield statistically significant over- or under-estimations when compared to the intraoperative findings independent of their age or gender. CONCLUSION: Our modus 3-D volumetry, when based on the "smallest" (native) unenhanced CT phase, accurately accounted for intrahepatic vascular volumes and offered a precise virtual model of individualized operative conditions for each potential live liver donor.
