螺旋CT仿真支气管镜与纤维支气管镜检查在较大气道病变诊断中的应用比较

Compare with CT virtual bronchoscopy and fiberoptic bronchoscopy clinical application in larger airway

目的探讨应用螺旋CT仿真支气管镜技术(CTVB)对较大气道病变诊断方法的应用价值。方法应用螺旋CT仿真支气管镜技术(CTVB)及纤维支气管镜(FOB)对30例较大气道病变的患者进行检查并分析比较两种方法的差异。结果发现CTVB在较大气道所获得气道管腔内壁、腔内病变及管腔形态等方面的图像效果与FOB所见基本相同,且可以显示严重狭窄、阻塞部位远端的情况,可为气道手术方案提供重要参考资料,但无法提供黏膜色泽及细微改变。结论CTVB对较大气道病变是一种很好的诊断方法。

To evaluation CT virtual bronchoscopy(CTVB) application in the larger airway disease. To compare the effectiveness and difference of CTVB and fiberoptic bronchoscopic (FOB)in the evaluation of the larger airway disease in 30 case patients. In all cases the lesions features visualizd with virtual display modality were confirmed by FOB, CTVB could provide important date for guideing operation pattern,it was also visualize areas beyond stenosis and occlusion, but CTVB could not show the colour and mini chang of airway′s mucosa. [Conclusion] CTVB is an useful technique of evaluation and diagnosis for the larger airway diseases.
