The radiographic and endoscopic findings of 83 consecutive patients with suspected foreign body (FB) inhalation into the tracheobronchial tree were compared and the accuracy of chest radiography was estimated. Typical radiologic signs of FB aspiration, such as localized air trapping, atelectasis and infection occurred on radiographs of patients with and without FB. Twenty-four percent of patients with endoscopically verified FB had no abnormalities on chest radiography. In an analysis of radiographs of 83 consecutive patients, in which the prevalence of FB aspiration was 41%, the diagnostic accuracy was 67%, sensitivity 68% and specificity 67%. Plain film radiology alone is not a sufficiently sensitive nor specific method for the diagnosis of FB aspiration.
对连续83例疑似气管支气管树吸入异物（FB）患者的影像学和内镜检查结果进行了比较，并评估了胸部X线摄影的准确性。FB误吸的典型放射学征象，如局限性气体潴留、肺不张和感染，在有或无FB的患者的X线片上均有出现。经内镜证实有FB的患者中，24%的胸部X线片无异常。在对83例连续患者的X线片分析中，FB误吸的患病率为41%，诊断准确性为67%，敏感性为68%，特异性为67%。单纯的平片放射学检查对于FB误吸的诊断既不够敏感也不够特异。
