摘要
作者报告４２例胆总管结石，ＣＴ诊断正确率为８５．７％。依结石的密度不同分为以下几类：（１）高密度结石（＞６０ＨＵ）；（２）软组织密度结石（２Ｏ～６０ＨＵ）；（３）低密度结石（＜２０ＨＵ）；（４）混合密度结石。对胆总管结石的ＣＴ表现及其诊断和鉴别诊断进行了讨论。
CT correctly diagnosed common bile duct stones in 36(85.7%)of 42 surgically proven cases.The stones were classified into 4 types according to their different densities:( 1)high density (>60HU);(2)soft tissue density(20～60HU):(3)low density (<20HU):and(4)mixed density. The CT signs,diagnosis and differential diagnosis of common bile duct stones、were dis-cussed.
