| 摘 要： | 目的探讨64层螺旋CT低剂量扫描重组成像在幼儿呼吸道异物诊断中的应用。方法对38例临床怀疑气管支气管异物的幼儿行低剂量螺旋CT扫描,记录每位患儿的平均有效剂量(mGy),扫描数据经后处理重建,包括多平面重组(MPR)、最小密度投影(MinIP)、仿真支气管镜(VB)。结果纤维支气管镜证实气管支气管异物32例,64层螺旋CT数据后处理结果清晰显示异物的部位、大小、形态及伴随征象MSCT均得到准确诊断。MPR能多角度清晰显示段以上气管支气管异物并能显示肺部并发症,优于MinIP、VB,可弥补横断位图像的不足。结论幼儿气管支气管异物MSCT低剂量扫描能满足诊断,准确评估异物大小、位置、形态及肺部并发症,对可疑呼吸道异物的诊断有重要临床价值。

| Abstract: | Objective To evaluate the value of low-dose multi-slice CT(MSCT)with post-processing techniques in the diagnosis of endo-tracheal/bronchial foreign objects in children.Methods 38 pediatric patients with clinically suspected endo-tracheal/bronchial foreign objects in children,underwent low-dose MSCT scanning.The mean effective dosage of radiation(mGy)was measured for all patients.The original scanning data were reconstructed with MPR,MinIP,and VB.Results Foreign objects were detected by conventional bronchos... |
