目的探讨螺旋CT后处理技术在诊断老年气管内异物中的应用及其价值。方法 40例疑似支气管内异物的老年患者,行螺旋CT扫描及三维重建处理,并与气管镜检查结果对照。结果 CT诊断气管内异物38例,未见明显异物2例;气管镜下诊断异物30例,未见异物10例;螺旋CT假阳性10例,假阴性2例。螺旋CT对老年气管内异物诊断的敏感度为93.3%,准确率为70.0%。结论 16层螺旋CT及其后处理技术对于老年气管内异物的诊断具有重要价值。
Objective To investigate the application and value of spiral CT postprocessing in the diagnosis of foreign tracheal foreign bodies. Methods A total of 40 elderly patients with suspected intrabronchial foreign bodies underwent helical CT scan and three-dimensional reconstruction. The results were compared with those of bronchoscopy. Results Thirty-eight cases of intra-tracheal foreign body were diagnosed by CT. There were no obvious foreign bodies in 2 cases. Thirty cases of foreign body were diagnosed by bronchoscopy and 10 cases of foreign body were not seen. CT was false positive in 10 cases and false negative in 2 cases. The sensitivity of spiral CT in the diagnosis of senile endotracheal foreign body was 93.3% with an accuracy rate of 70.0%. Conclusion 16-slice spiral CT and its post-processing techniques are of great value in the diagnosis of foreign tracheal foreign bodies.
