摘要
目的探讨螺旋CT对小儿气道异物的临床诊断价值。方法分析18例小儿气道非金属异物患者的螺旋CT表现。结果薄层横断位像能提示病变所在部位。MPR像直观显示异物大小、密度及气道管壁形态。SSD,RT3D像立体地显示异物与气道的形态及关系。其他技术可验证上述所见。CT显示完全阻塞11例,部分阻塞7例。病变呈软组织或稍高密度的不规则或圆形腔内病变。并可见肺内炎症、肺气肿、肺不张、纵隔移位及双边影、胸壁双边影等间接征象表现。结论螺旋CT多种技术方法成像显示小儿气道异物直观准确,具有重要的临床应用价值。
Objective To discuss the diagnostic value of spiral CT for intrabronchial foreign body in childhood. Methods CT findings of 18 children with intrabronchial non - metallic foreign bodies were analyzed. Results Axial thin slice imaging could suggest the location of the lesions. Multi - planar reconstruction （MPR）imaging directly revealed the size and density of intrabronchial foreign bodies and the shape of airway walls. Surface shaded display（SSD） and RT3D imaging stereoscopically revealed the shape of the foreign bodies and their relation with airway. Above these findigs were confirmed by other imaging techniques. Of 18 cases, the complete obstruction and partial obstruction of the airway were found in 11 cases and 7 cases, respectively. The lesions presented as intracavitary soft tissue masses and irregular or round masses with slightly high density. In addition, some mediate signs such as pulmonary inflammation, emphysema, atelectasis, mediastinal shift and double edge shadows of mediastinum and thoracic wall were more or less found in the group. Conclusion Using multiple imaging techniques of spiral CT can accurately reveal the size , shape and location of the foreign bodies so that spiral CT has important value for diagnosing this disease.
