目的 :探讨肝内胆管结石的 CT表现及诊断价值。方法 :对 6 5例肝内胆管结石的 CT征象进行分析 ,并与超声对照。结果 :(1) CT诊断肝内胆管结石的准确率达 98.5 % ;(2 )因结石的密度不同可分为四类 ,即高密度、软组织密度 ,低密度和混杂密度结石 ;(3)肝内胆管扩张以局限性囊、柱状扩张为特征 ;(4 ) CT可准确显示和诊断其合并症。结论 :CT是肝内胆管结石有效的诊断手段 ,其诊断准确性特别是对并发症的诊断优于 B超
Objective: To investigate the CT findings and diagnostic value of intrahepatic bile duct stones. Methods: The CT findings of 65 cases of intrahepatic bile duct stones were analyzed and compared with ultrasound. Results: (1) The accuracy rate of CT diagnosis of intrahepatic bile duct stones was 98.5%. (2) Because of the different density of stones, it could be divided into four categories: high density, soft tissue density, low density and mixed density stones; Intrahepatic canal expansion to the limitations of the capsule, columnar dilation characterized; (4) CT can accurately display and diagnose its complications. Conclusion: CT is an effective diagnostic method for intrahepatic bile duct stones. The diagnostic accuracy of CT is better than that of B ultrasound
