Abstract:
The CT findings and diagnosis of 39 operatively verified cases of bile duct stone are analysed. All the cases are studied with CT,part of the cases are studied with ultrasonography, ERCP and PTC. The direct CT findings, the intrahepatic biliary duct stones display high attenuation shadow or soft tissue density (20/23); the extrahepatic biliary duct stones display target sign or high attenuation shadow in the pancreatic head (14/24). The indirect findings show the dilatation of the intrahepatic biliary system.The extrahepatic biliary duct stone also shows dilatation of the distal common bile duct (CBD) with gradually fining away. CT diagnosis of the bile duct stone is considered to base on the direct findings with reference of the indirect findings and synthesized diagnosis.The thin slice scanning technology can press the visible rate of the CBD stone (it should be a routine studying method of the CBD stone). The method of imaging diagnosis of the biliary duct stone is also discussed.
