摘要
目的探讨多层螺旋CT(MSCT)在诊断支气管异物中的临床应用价值,提高对支气管异物影像学表现认识。方法回顾性分析15例经临床证实的支气管异物患者的MSCT扫描及重组图像的影像学表现。结果15例支气管异物胸片有"三阻征"的间接征象:阻塞性肺炎、肺气肿、肺不张。MSCT可显示支气管异物的位置、形态、大小及异物所致支气管狭窄和堵塞情况。结论MSCT及图像后处理技术在支气管异物诊断中具有重要的临床应用价值,可以成为本病的首选检查方法。
Objective To discuss the value of multislice spiral computed tomograph （ MSCT ） in diagno- sing the Trachea Foreign body in order to improve the understanding of the imaging presentation of Trachea Foreign body. Methods The imaging presentation of 15 cases with bronchial foreign body by MSCT and its reconstructive imaging were retrospectively analyzed. Results 15 cases had the indirect sign called＂ three obstructive signs＂, which includes obstructive pneumonia, obstructive emphysema, obstructive atelectasis. MSCT could display all of the condition resulting from bronchial foreign body about its location, shape and size,endobronchial stenosis and occlusion. Conclusion MSCT and imaging reconstruction techniques are valuable in judging bronchial foreign body, which can be used as the first choice.
