Three-dimensional Fusion Images of Hepatic Vasculature and Bile Duct used for Preoperative Simulation before Hepatic Surgery

Background/Aims: Recent developments in radiological technology allowed acquisition of images with high spatial resolution that facilitate effective 3-dimensional (3D) reconstruction 25 of fusion images. Present study utilized 3D cholangiography and angiography with multidetector-row computed tomography (MDCT) to acquire information regarding operative simulations. Methodology: 3D-fusion images were evaluated in 39 patients with hepatobiliary malignancies who underwent surgical resections. 30 Results: An aberrant branch of segment 3 over the umbilical portal vein, a large hepatoma compressed the hilar vessels, an aberrant branch of the caudate lobe vasculature in case of metastatic liver tumor with a right-sided umbilical portal vein and transected biliary leakage were clearly observed by 3D imaging system. Four patients with intrahepati
