A double-blind, controlled study to assess the accuracy of interpretation of lateral soft tissue radiographs of 60 patients with suspected foreign body impaction in the oro/hypopharynx was carried out by 18 respondents from three different specialities. All the patients had endoscopy carried out and foreign bodies were present in 25. Of these, foreign bodies were diagnosed on the radiograph in only 38.3 per cent. False-positive diagnoses were made in a mean of 26.3 per cent of those patients who did not have a foreign body.
一项双盲对照研究对60例疑似口咽/下咽有异物嵌顿的患者的侧位软组织X线片解读准确性进行了评估，由来自三个不同专业的18名受试者参与。所有患者均接受了内镜检查，其中25例存在异物。在这些患者中，X线片仅诊断出38.3%的异物。在没有异物的患者中，平均有26.3%被误诊为阳性。
