Intrahepatic bile duct carcinoma diagnostic CT
【Objective】 to study the spiral CT in diagnosis of liver bile duct carcinoma portal vein of value. Methods: a retrospective analysis of 21 cases of liver portal vein bile duct carcinoma CT scan and enhance the flat esau performance. Key observation tumor in the morphological characteristics, intrahepatic bile ducts dilation degree, limits, liver vascular invasion by the portal vein and parenchymal visceral with surrounding metastases. Conclusion: spiral CT arterial, portal period, delay period scanning is beneficial not only to observe liver lobectomy in strengthening and morphological characteristics, is more advantageous to observe the peripheral vascular tumor inolement situation and intrahepatic without son foci ......
