摘　　要：Hilar cholangiocarcinoma is a rare malignant tumor arising from the epithelium of the bile ducts.Surgery is still the only chance of potentially curative treatment in patients with perihilar cholangiocarcinoma.However,radical resection requires aggressive surgical strategies that should be tailored optimally according to the location,size and vascular invasion of the tumors.Accurate diagnosis and staging of these tumors is therefore critical for optimal treatment planning and for determining a prognosis.Multidetector computed tomography(MDCT),magnetic resonance imaging(MRI) and MR cholangiography are useful tools,both to diagnose and stage hilar cholangiocarcinoma.Modern imaging techniques allow accurate detection of the level of obstruction and the longitudinal and radial spread of the tumor.In addition,high-resolution MDCT and MR provide specific radiographic features to determine vascular involvement of anatomic structures,such as the hepatic artery or the portal vein,which are critical to decide the surgical strategy.Finally,radiological staging allows detection of patients with distant metastasis in the liver or peritoneum who will not benefit from a surgical approach. 关键词：CHOLANGIOCARCINOMA RADIOLOGICAL STAGING Magnetic resonance imaging MULTIDETECTOR COMPUTED tomography Hepatic RESECTION
