| 摘 要： | 目的:评价低剂量多层CT及其重建在小儿支气管异物中的诊断价值。方法:15例临床怀疑支气管异物患儿,全部采用低剂量进行CT扫描,并结合多平面重建(MPR)、表面遮盖法(SSD)和仿真支气管镜(CTVB)等重建图像进行分析,结果与纤支镜对照。结果:发现异物17枚,支气管镜证实并取出18枚,诊断符合率93.3%。结论:低剂量CT扫描不仅能够减少小儿所接受的辐射剂量,图像重建的结果对支气管异物诊断的准确率较高,可作为支气管镜检查前的筛查与定位手段。

| Abstract: | Objective:To evaluate low-dose multi-slice spiral CT(MSCT) reconstruction in the diagnosis of bronchus foreign of body chidren. Methods:Fifteen children suspected bronchus foreigh bodies were all checked by low-dose spiral CT combinated with multiplannar reconstruction(MPR), shaded surface display(SSD),and virtual bronchoscopy(CTVB), compared with the fiberoptic bronchoscopic findings.Results:17 foreigh bodies were found by MSCT, 18 foreigh bodies were retracted and extracted by fibreoptic bronchoscope. Compared with MSCT, the rate of conformed diagnosis was 93.3%. Conclusion:Low-dose spiral CT reconstruction displays bronchus foreign well, can locate them accurately. |
