肝内胆管结石的16排螺旋CT诊断价值

Diagnostic Value of CT on Calculus of Intrahepatic Duct

目的 探讨肝内胆管结石的CT征象,评价其16排螺旋CT扫描的诊断价值。方法 回顾性分析28例肝内管结石的CT征象及临床表现,并与超声检查对照。结果 本组28例肝内胆管结石患者（伴Caroli氏病1例）,根据结石密度可分成4类：高密度结石（〉60HU）18例,软组织密度结石（20-60 HU）3例,低密度结石（〈20 HU）2例,混杂密度结石5例。结论 16排螺旋CT对肝内胆管结石的诊断准确性较高,特别是对并发症的诊断优于超声。CT和超声结合,能够达到最佳的诊断效果。

Objective To probe into the diagnostic value of 16 muhislice spiral CT on calculus of intrahepatic duct （ CID ） with the signs on CT scan, Methods The clinical materials of 28 cases such patients were analyzed and compared in CT scan and sign, clincal manifestation and ultrasound results retrospectively, Results The density of calculus had divided into high density of 18 cases, soft tissue density of 3 cases, low density of 2 cases and mixed density of 5 cases. Conclusions 16 muhislice spiral CT scan might have high value to obtain the diagnosis of CID and it＇s better to combined with ultrasound detection to diagnosis best.
