摘要/Abstract

摘要： 目的评价多层螺旋CT(multilayer spiral computed tomography，MSCT)三维重建对气管支气管异物诊断的价值。方法对30例怀疑为气管支气管异物的患者，实施肺螺旋CT平扫及三维重建,与硬性支气管镜下手术情况对比，分析各种重建方法对支气管异物的显示情况及诊断价值。结果 30例患者均获清晰图像，23例异物部位与术中所见一致,出现位移1例,假阴性1例，异物咳出后检查3例, 左主支气管狭窄1例，吸入性肺炎1例，均未见异物。各种重建方法均可清楚显示气管、支气管异物的位置、形状、大小及异物所致气管、支气管狭窄的部位、程度和外形改变。结论螺旋CT及图像后处理技术在气管支气管异物诊断中具有重要的临床应用价值。

Abstract: Objective To investigate the value of the CT 3D in the diagnosis of tracheobronchial foreign bodies. Methods 30 patients suspected of having tracheobronchial foreign bodies were subjected to HRCT scanning and 3D reconstruction. Images by HRCT and those under the stiff bronchoscope were compared to analyze the value of reconstruction. Results All 30 patients gained clear images. Foreign bodies were found at the same position shown by CT and operations in 23 patients, while they were moved in one, and they were negative in 3 patients examined by CT. One showed false negative images. Stiff bronchoscopy proved that one had a left bronchiostenosis and the other had inhalant bronchitis. Conclusions MSCT and imaging retro-processing techniques are valuable in judging tracheobronchial foreign bodies.
