摘要
目的 :探讨气管、支气管冠状位CT扫描诊断小儿支气管异物敏感性、特异性及临床应用价值。方法 :对 30例支气管异物患儿摄X线胸片及胸透检查 ,同时行气管、支气管冠状位CT扫描 ,其中 18例患儿行CT轴位扫描进行对照。结果 :30例CT冠状位扫描均清晰显示支气管腔内异物及异物周围炎性肉芽肿 ,其中阻塞性肺气肿 2 8例、阻塞性肺炎 5例、阻塞性肺不张 3例。结论 :气管、支气管冠状位CT扫描可以显示小儿支气管异物的直接征像和间接征像 ,其显示异物所在的位置对指导手术有重要意义。
Objective:To study the sensitivity,specificity and clinical value of coranal CT scan of trachea and bronchus in diagnoing children's foreign body in bronchus.Method:30 cases of the children with foreign body in their trachea and bronchus were examined by chest X ray (chest X rays ), and by coranal CT scan at the same time.( some of them were compared with axial CT scan.) Result:The position of foreign body in trachea and bronchus was definitely diagnosed by coranal CT scan in all cases,of whom,28 cases with obstructive emphysema;5 case with obstructive pneumonia and 3 cases with obstructive atelectasis.Conclusion:Coranal CT scan could demonstrate the position of foreign body in trachea and bronchus and be helpful in planning surgery.
