摘　　要：目的　探讨多层面螺旋CT胆道仿真内窥镜 (Multi-slicehelicCTvirtualcholangioscopy,MSCTVC)在胆管系统结石诊断中的检查方法和临床应用价值。方法　选择 38例经B超检查后诊断为胆管系统结石的患者外周静脉滴注 5 0 %胆影葡胺 2 0ml行多层面螺旋CT容积扫描 ,将容积数据薄层重建后传输至工作站 ,利用Navigator导航软件重建成仿真内窥镜图像 ,全部病例经B超、CT轴位图像、多层面螺旋CT三维成像 (SSD、MIP、Raysum)证实。结果　多层面螺旋CT胆道仿真内窥镜可精确显示结石所在部位、结石的形态、大小 ,与B超、多层面螺旋CT二维 (轴、矢、冠状位 )图像及三维成像 (SSD、MIP、Raysum)具有良好的对应性 ,尤其对于在轴位CT不能显示的阴性结石通过胆道仿真内窥镜可清晰显示。结论　MSCTVC结合CT二维、三维图像对胆管结石的诊断有较高的准确性和临床使用性 ,提高了胆管系统结石的诊断能力。Objective To investigate the methods and clinical value of multi-slice CT virtual cholangioscopy in the detection of biliary calculus.Methods Volume scanning was performed in 38 patients with suspected biliary calculi after injection 50% Meglumine adipiodone injection 20 ml through vien.All data sets were transferred to ADV3.1 workstation.MSCTVC reconstruction were done with Navigator soft-ware.All cases were proved by ultrasound,axial CT and MSCT 3 D results or operations.Results MSCTVC could well demonstrate 3D fashion of biliary calculi and it was similar to ultrasound,axial CT and MSCT 3D results.Conclusion MSCTVC combined with CT 2D 3D results has a high diagnosis accuracy and clinical usefulness,thus,improve the diagnosis of biliary calculi.
