Fig. 1. Technical steps for hepatic venous territory mapping. Using the Volume viewer in the AW server (GE Healthcare), (A) hepatic parenchyma is 3-dimensionally mapped and volume is calculated excluding the volume of major vessels. (B) As the hepatic venous branches are labeled, (C) it is combined with the parenchyma to divide the districts based on the venous territories. IHV, inferior hepatic vein; RHV, right hepatic vein.
