Core tip: Tumors of the biliary tree are relatively rare; but their incidence is rising worldwide. When biliary disease is suspected, magnetic resonance imaging (MRI) can often help differentiate between benignity and malignancy, stage tumors, select surgical candidates and guide surgical planning. Nowadays remarkable technical advances in magnetic resonance technology have expanded the clinical applications of MRI in case of biliary diseases. In this article, it is also discussed how recent developments in MRI contributes to the diagnosis of the bile duct cancer and the evaluation of patients with risk factors affecting bile duct cancer.
