摘要
目的探讨放射影像技术对小儿气管支气管异物的诊断价值。方法任意选取56例2017年1月至2019年1月在本院接受诊治的小儿气管支气管异物患者为研究对象,分别予以X线和CT检查,进行检出率、异物征象检出率和成像质量的对比。结果 CT诊断的检出率为96.4%,与X线检查相比,差异具有统计学意义(P<0.05);CT对支气管阻塞的检出率为94.6%,纵膈位置改变检出率为57.1%,肺炎检出率为35.7%,肺气肿检出率为85.7%,明显高于X线检查的71.4%、30.4%、12.5%和64.3%,差异具有统计学意义(P<0.05);CT检查Ⅰ级成像质量概率为87.5%,Ⅱ级成像质量概率为8.9%,Ⅲ级成像质量概率为3.6%,相比于X线检查的53.6%、25.0%和21.4%,差异具有统计学意义(P<0.05)。结论与X线检查相比,CT诊断方式可明显提高小儿气管支气管异物的诊断价值,利于清晰显示异物征象,成像质量高,值得推广应用。
Objective To evaluate the diagnostic value of radiography in children with tracheobronchial foreign bodies. Methods 56 children with tracheobronchial foreign bodies treated in our hospital from January 2017 to January 2019 were randomly selected and examined by X-ray and CT. The detection rate, the detection rate of foreign bodies and the imaging quality were compared. Results The detection rate of CT was 96.4%,which was significantly higher than that of X-ray(P<0.05). The detection rate of CT for bronchial obstruction was 94.6%, the detection rate of mediastinal position change was 57.1%, the detection rate of pneumonia was 35.7%, and the detection rate of emphysema was 85.7%, which were significantly higher than that of X-ray examination(71.4%, 30.4%, 12.5% and 64.3%). The difference was statistically significant(P<0.05). CT examination grade Ⅰ imaging quality probability was 87.5%, Ⅱ level image quality probability by 8.9%, Ⅲ level image quality probability was 3.6%, compared with the X-ray were 53.6%, 25.0% and 21.4%, the difference was statistically significant(P<0.05). Conclusion Compared with X-ray examination, the diagnostic method of CT is obvious. To improve the diagnostic value of tracheobronchial foreign bodies in children, to clearly display the signs of foreign bodies, high imaging quality, it is worth popularizing and applying.
