title: [Clinical value of MR cholangiopancreatography combining with dynamic enhanced MRI in the detection of cholangiocarcinoma].
abstract: OBJECTIVE
  To evaluate the clinical value of breath-hold magnetic resonance cholangiopancreatography (MRCP) combining with dynamic enhanced MRI in the diagnosis of cholangiocarcinoma.
  
  
  METHODS
  MRCP findings of 88 cholangiocarcinoma patients proved surgically and pathologically were analyzed retrospectively.
  
  
  RESULTS
  MRCP examination succeeded in all the 88 patients and the pancreaticobiliary ducts were shown satisfactorily. The accuracy of MRCP in the location of both hilar and extrahepatic cholangiocarcinoma was 100%, and the accuracy of detecting hilar and extrahepatic cholangiocarcinoma were 100% and 52.2%, respectively. Combining with dynamic enhanced MRI, the detecting accuracy of extrahepatic cholangiocarcinoma improved to 91.3%.
  
  
  CONCLUSIONS
  MRCP examination has a high successful rate and can accurately determine the location of hilar and extrahepatic cholangiocarcinoma, and the accuracy of qualitative diagnosis for the former two is high. Combining with dynamic enhanced MRI, the specificity of determining extrahepatic cholangiocarcinoma is also high.
