梗阻性黄疸的多层螺旋CT诊断

目的探讨多层螺旋CT(MSCT)在诊断良、恶性梗阻性黄疸中的价值。方法 32例有梗阻性黄疸的住院患者,进行多层螺旋CT检查,平扫层厚和间隔为5mm-10mm,增强扫描增厚和间隔为5-10mm,对原始数据进行层厚为2-3mm,间隔为2-3mm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95%。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。

Purpose Application of multislice helical CT(MSCT) in the diagnosis of benign、value of malignant obstructive jaundice.Methods In32 patients with obstructive jaundice patients,multilayer spiral CT examination,scan slice thickness and spacing of 5 mm-10 mm,Enhanced thickening and interval of 5-10 mm,the original data layer thickness of 2-3 mm,Interval of 2-3mm reconstruction,The incoming MPR、SCTC processing workstation,on the localization and qualitative diagnosis of bile duct obstruction evaluation,operation and pathology.Outcome multi slice spiral CT in obstructive jaundice positioning and qualitative accuracy rates were 95%.Conclusion multi slice spiral CT has powerful processing function,on obstructive jaundice positioning and qualitative accuracy,Is an excellent noninvasive screening method.
