螺旋CT及其后处理在胆管结石中的诊断价值

Diagnostic value of spiral CT and subsequent processing in the bile duct calculus

目的:探讨螺旋CT及其后处理技术在胆管结石中的应用价值。方法:40例胆管结石患者给予螺旋CT及其后处理,进行结石病的定位、定性诊断,并与手术结果相比。结果:螺旋CT及其后处理技术对肝内胆管、胆总管结石的诊断符合率分别为90%(9/10)、89%(31/35),对高密度结石、等低密度结石的诊断符合率分别为100%(42/42)及75%(6/8)。结论:螺旋CT及其后处理技术是诊断胆管结石的有效检查方法,尤其对高密度结石有极高的诊断价值。

Objective:To explore the application value of spiral CT and subsequent processing technology in the bile ductcalculus.Methods:40 patients with bile duct calculus were given spiral CT and subsequent processing.The localization andqualitative diagnosis of stone disease were given and compared with the operation results.Results:The diagnose accordance ratesof spiral CT and subsequent processing technology in the intrahepatic bile duct,common bile duct calculus were respectively 90%(9/10)、89%(31/35).The diagnose accordance rates of high density calculus and low density calculus were respectively 100%(42/42) and 75%(6/8).Conclusion:The spiral CT and subsequent processing is an effective inspection method in the diagnosis of bileduct calculus,especially it has a sky-high diagnostic value of high density calculus.
