Two observers retrospectively evaluated 3D\u2010MRCP and ERCP\/PTC and recorded the level of obstruction and extent of tumor along with their confidence. The quality of images and morphologic appearance of stricture were also evaluated by two reviewers. The results of MRCP and ERCP\/PTC were compared with surgical and histopathological data.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>3D\u2010MRCP was of diagnostic quality and free of artifacts in all patients, whereas ERCP\/PTC examinations failed in three patients. For the evaluation of level of obstruction, there was no statistical significance between 3D\u2010MRCP and ERCP\/PTC. 3D\u2010MRCP was superior to ERCP\/PTC in the assessment of anatomical extent of hilar bile duct involvement, but did not show statistical significance. The accuracy of 3D\u2010MRCP in determining tumoral extent of hilar cancer was higher than that of ERCP\/PTC, but it was not statistically significant. The image quality of 3D\u2010MRCP was superior to ERCP\/PTC.
