摘　　要：目的：探讨阻塞性黄疸的ＣＴ诊断特点。方法：通过对肝、胆、胰ＣＴ表现的影像特征分析，探讨不同部位梗阻和不同性质病变时的影像特征差异。结果：肿瘤和结石是引起阻塞性黄疸的重要原因。肿瘤引起肝内胆管扩张的程度明显大于结石所引起的（Ｐ＜０．０５），二者对肝外胆管扩张程度的影响差异不显著（Ｐ＞０．０５），胆管炎可引起起间断性阻塞性黄疸，但肝内外胆管扩张程度常不显著。梗阻近端扩张，远端萎缩是普遍特征。胆总管未端形态和密度变化的分析对鉴别诊断尤为重要。结论：肿瘤和结石是引起阻塞性黄疸的重要原因。Objective:CT manifestations of liver,gall and pancreas were studied in 35 obstructive jaundice cases,which was caused by different pathogeny and confirmed by operation and pathology.Results: Tumor and stone were important factors causing obstructive jaundice.Futhermore,the CT manifestations of pancreas as well as gall were different according to different causes.Conclusion:The analysis on every kind of CT signs could provide important evidence for the correct diagnosis of obstructive jaundce.
