摘　　要：目的探讨气管、支气管冠状位MRI扫描诊断小儿气管异物的临床应用价值。方法对33例气管、支气管异物患儿行气管、支气管冠状位MRI扫描,其中25例并行摄X线胸片及胸透检查进行对照。结果31例MRI冠状位扫描均清晰显示气管、支气管腔内异物,其中阻塞性肺气肿9例、阻塞性肺不张8例、阻塞性肺炎5例。2例排除异物。结论气管、支气管冠状位MRI扫描可以显示小儿气管异物的直接征像和间接征像,显示异物所在的位置对指导手术有重要意义。Objective To study the clinical value of coranal MRI scan of trachea and bronchus in d iagnosing children's foreign body in bronchus.Method33cases of the children with foreign body in their trachea and bronchus we re examined by coranal MRI scan ,25case s were examined by chest X ray at the sa me time.Results The position of foreign body in trachea and bronchus was definitely diagnosed by coranal MRI scan in of 31cases,of whom,9cases with ob structive emphysema;8cases with obstructive atelectasis and 5cases with obstructive pneumonia;2case was excluded t he foreign body in trachea.Conclusion Coranal MRI scan could demonstrate t he of foreign body in trachea and bron chus and be helpful in planning surgery.
