Aim: To evaluate the accuracy of Magnetic resonance cholangiography (MRC) in defining the extent of biliary ductal involvement in malignant hilar obstruction and its usefulness in planning percutaneous palliative drainage. Materials and Methods: Fifteen patients with malignant hilar obstructions were examined with MRC. All patients underwent Percutaneous Transhepatic Cholangiography (PTC) and biliary drainage. The site of obstruction and a hypothetical drainage plan based on the MRC findings were compared to the PTC and the actual drainage performed. Results: MRC accurately predicted the site of obstruction in 11 out of 14 patients (78 percent). One patient had an inadequate MRC. The hypothetical drainage plan based on MRC matched the actual drainage in 12 out of 14 cases (85 percent). Conclusion: Preprocedural MRC is a valuable tool for defining the site of obstruction. It provides a 'road map' for performing percutaneous biliary drainage.
