[Use of three-dimensional reconstruction of the biliary tree in spiral computed tomography without using hepatotropic contrast media].
The aim of the study was to assess the quality of biliary tract imaging without cholangiographic contrast medium and to evaluate the usefulness of 3-D reformations in determination of ductal anatomic relationship. The spiral 5 mm CT liver scans were performed after a bolus of 150 ml i.v. contrast agent in 15 patients with a malignant obstructive jaundice. The biliary tract was separated from surrounding hepatic parenchyma with segmentation computer algorithm and then 3-D models were produced. In all the patients, both biliary anatomy and the localization and degree of segmental obstruction were visualized with satisfying quality. The 3-D sCT models of dilated biliary tract can be obtained without cholangiographic contrast agent and can clearly depict ductal anatomy and pathology.
