目的：探讨多层螺旋CT对气道异物的诊断价值。方法对门诊收治疑似气管异物患者56例，给予多层螺旋CT检查，并与支气管镜检查作对照。结果多层螺旋CT检查共检出气道异物患者52例，1例误诊为肺炎，后经气管镜检查并取出异物，漏诊2例，假阳性1例。多层螺旋CT检查及气管镜对气道异物检出率差异无统计学意义（χ2＝0.61， P ＞0.05）。以支气管镜检查结果为金标准，螺旋 CT 灵敏度为96.23％，特异度为66.67％，诊断符合率为94.64％。结论多层螺旋CT检查气道异物，具有灵敏度高、符合率高特点，诊断时应结合病史、临床体征，以降低误诊率、漏诊率。儿童检查应以最低剂量扫描，避免辐射损伤。

Objective To investigate the value of multislice CT in the diagnosis of airway foreign bodies . Methods Fifty-six patients with suspected airway foreign body were given multislice CT examination , and their ex-amined results were contrastod with the results obtained by bronchoscopy .Results Multislice CT examination detec-ted airway foreign body in 52 patients, 1 case was misdiagnosed as pneumonia , and the foreign body was removed by bronchoscope examination;Between multislice CT and bronchoscope there was no statistically difference in foreign body detection rate (χ2 =0.61 , P>0.05 ); With bronchoscope examination results as the gold standard , spiral CT sensitivity was 96.23%, the diagnostic coincidence rate was 96.64%.Conclusion Multislice CT examination for airway foreign bodies have the characteristics of high sensitivity , high coincidence rate , but also should be combined with the history, clinical signs, in order to reduce the incidence of misdiagnosis , missed diagnosis.For children, multislice CT examination should be penformed at the lowest dose scanning , in order to avoid radiation damage .
