| 中文摘要:目的探讨螺旋CT三维重建技术在儿童呼吸道异物诊断中的应用价值。方法对可疑儿童呼吸道异物进行螺旋CT扫描及三维重建，结果作为研究组；以气管镜检查结果作为金标准，X线胸片或胸透检查结果作为对照组，通过χ2检验比较两组与金标准符合情况。结果螺旋CT三维重建可清楚显示病变部位、范围、有无继发感染，其阳性率高于对照组，差异具有统计学意义 （P<0.05）。结论螺旋CT 三维成像技术是诊断儿童呼吸道异物的重要依据。 |

| Abstract:ObjectiveTo evaluate the value of spiral CT three dimensional (3D) reconstructions in the diagnosis of tracheo-bronchial foreign bodies in children. MethodsThe spiral CT scan and 3D reconstruction images were regarded as the study group,and chest X-ray and fluoroscopy examinations as the control group.The results were compared with the gold standard of tracheoscope examination using the Chi-square test.Results3D reconstructions of spiral CT could well display the location, range and secondary infection of tracheo-bronchial foreign bodies, which had a high positive proportion and stastistical significance (P<0.05). Conclusion3D reconstruction technique of spiral CT is valuable in the diagnosis of tracheobronchial foreign bodies in children. |
