[摘 要] 目的：探讨多层螺旋CT(MSCT)在梗阻性黄疸诊断中的临床应用价值。方法：70例经B超检查提示有肝内外胆管梗阻的患者，进行多层螺旋CT检查，平扫层厚和间隔为5 mm～10 mm，增强扫描增厚和间隔为5 mm，对原始数据进行层厚为2.5 mm，间隔为1.25 mm重建，传入工作站进行MPR、SCTC处理，对胆管梗阻定位和定性诊断作出评价，并与手术病理对照。结果：多层螺旋CT对梗阻性黄疸定位和定性准确率分别为100%和90%。结论：多层螺旋CT具有强大的后处理功能，对梗阻性黄疸定位和定性准确率高，是一种很好的无创性检查方法。[关键词] 梗阻性黄疸；诊断；多层螺旋CT

Abstract:Objective To approach the value of clinical application in the diagnosis of obstructive jaundice.with multislice spiral.Methods MSCT enhancing scaning was performed in 70 cases with obstructive extrahepatic bile duct disease.Plan scan thickness and interval in 5 cm～10 cm,volume scan，arterial phase and hepatic parenchymal phase scanafter enhancement，thickness and interval in 5 cm～10 cm.The row data of hepatic parenchymal phase was first reformatted to bing out axial source images(ASI).The data of ASI were transferred to workstation and MPR，SCTC was proceseed.Results Mscthave 100 and 90 rate in the accuracy of location and characterization in the obstruction.Conclusion MSCT have powerful aftertreatment ......
