The purpose of this prospective study was to assess the added value of the hepatocyte specific contrast agent gadoxetate disodium for characterization and staging of tumors in patients with malignant central bile duct stenosis. Intraoperative findings were used as gold standard. The results of our study show, that the application of gadoxetate disodium improves assessment of tumor extension, which is necessary to define tumor resectability. In this context images acquired in the late hepatocyte phase proved most useful for exact tumor delineation.
