摘　　要：目的探讨多层螺旋CT低剂量扫描在气管、支气管异物中的诊断价值。方法选取35例气管和支气管异物患者行胸部低剂量扫描,与支气管镜对比。结果多层螺旋CT低剂量扫描诊断气管异物9例,支气管异物26例,支气管镜取出异物34例,1例为黏液栓,多层螺旋CT低剂量扫描显示结果与支气管镜诊断结果在气管、支气管异物病例中的符合率为97%,多层螺旋CT后处理技术对于气管支气管异物的精确定位准确。结论多层螺旋CT低剂量扫描在明显降低辐射剂量的前提下,对诊断气管异物具有很高的诊断价值。Objective To explore the value of low-dose spiral CT scanning in the diagnosis of tracheobronchial foreign bodies. Methods Selected 35 cases with tracheal and bronchial foreign bodies carrying out row multislice CT chest low dose scan and Compare with the result of the bronchoscope. Results Nine cases for trachea, 26 cases for Bronchial foreign bodies, 34 cases with Bronchoscopy to remove the foreign body, 1 case for the mucus plug, Multilayer spiral CT scan can show the results of bronchoscopic diagnosis for tracheal and bronchial foreign body in accordance with rate of 97%, Pro cessing technology for precise positioning to the tracheobronchial foreign bodies in the rnuhislice CT is extremely accurate. Conclusion Under the premise of reduction in radiation dose of low dose muhislice spiral CT scan, we found that there is a high diagnostic value in the diagnosis of tracheobronchial foreign body.
