Abstract:Objective:To evaluate the value of MSCT in the diagnosis of cholangiocarcinoma.
Methods : A retrospective study was undertaken in 82 patients with cholangiocarcinoma, in which 38 had singleslice CT(SSCT), and 44 had multislice CT（MSCT) including 11 with delayed scanning.
Results:On CT scanning, the lesions′ characteristics were varied,depending on their growth pattern, while the indirect CT features were specific,like dilated bile duct, hepatic lobe atrophy,etc. The accuracy in location and assessment of extent of infiltration of the lesion by singleslice CT and multislice CT was 82.4％，97.4％and 52.9％，81.0％ respectively.
Conclusions:MSCT scan is superior to SSCT in diagnosis of cholangiocarcinoma.
