| ［摘要］ 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。 |

| ［Abstract］ 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 examined results were contrastod with the results obtained by bronchoscopy.Results Multislice CT examination detected 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. |
