Preoperative chest X-rays were taken in both postanterior and partially lateral views of 94 children with foreign-body aspiration. Additional fluoroscopy was employed in 70 patients. In 7% of the cases, the foreign body was radiopaque; in an equal amount of cases, there were no radiological findings. In the remaining results we observed: emphysema as an indirect radiological sign in two-thirds of the cases; in less than one-third, poststenotic atelectasis; pneumonia in 10%; bronchitis in 9%; pneumothorax in 2%.
对94例有异物吸入的儿童进行了术前胸部X线正位及部分侧位摄片。70例患者还进行了额外的透视检查。7%的病例中异物为不透射线的；同样比例的病例中无放射学表现。在其余病例中我们观察到：三分之二的病例有肺气肿作为间接放射学征象；不到三分之一的病例有狭窄后肺不张；10%的病例有肺炎；9%的病例有支气管炎；2%的病例有气胸。
