目的:探讨各种影像学检查在儿童透光异物诊断中的重要作用和价值。方法:对100例8个月~12岁就诊的患儿影像学检查发现气管有透光异物,并经纤维支气管镜取出证实。结果:100例患儿中X线透视和胸片检出11例,CT轴位和冠状位及螺旋CT检出98例。结论:气道异物的存在将直接危害儿童生命,也可因异物的存在造成肺炎、肺不张。CT轴位加冠状位、螺旋CT检查分辨率高,能清楚显示透光异物部位、大小、形态以及毗邻的关系,是一种有效、安全、无创的检查方法。
Objective: To explore the important role and value of various imaging examinations in the diagnosis of translucent foreign bodies in children. Methods: 100 cases of children from 8 months to 12 years of age were examined by imaging examination of the trachea with light-emitting foreign body, and confirmed by bronchoscopy. Results: Eleven cases were detected by X-ray and chest X-ray in 100 cases. There were 98 cases detected by CT axial and coronal scan and spiral CT. Conclusion: The existence of airway foreign bodies will directly endanger the life of children, but also cause pneumonia and atelectasis due to the presence of foreign bodies. Coronal CT axial position, spiral CT examination of high resolution, can clearly show the location of translucent foreign body, size, shape and the adjacent relationship is an effective, safe, noninvasive examination.
