计算机X线断层照像术在支气管异物诊断中的意义

Significance of Computed Tomography in Diagnosis of Bronchial Foreign Body in Children

目的探讨计算机X线断层照像术(CT)在儿童支气管异物诊断中的临床意义。方法对21例可疑支气管异物的患儿进行螺旋CT横断面扫描和冠状面重建,采用支气管镜术证实诊断。结果患儿均显示异物的直接征象,CT显示异物位于右肺主支气管12例,右中间支气管1例,右下叶支气管2例,左肺主支气管6例。支气管异物均经支气管镜术取出。结论CT扫描可显示儿童支气管异物,并能精确定位,对病史、体征和常规X线表现不典型的患儿有重要诊断价值。
