摘要
目的 研究螺旋ＣＴ仿真支气管镜（ＣＴＶＢ） 的临床应用价值。方法 对２５ 例患者进行ＣＴＶＢ检查，其中２２ 例经纤维支气管镜（ＦＯＢ） 检查，并将二者所见表现对照分析。结果 ＣＴＶＢ 获得的图像效果类似纤维支气管镜镜下所见的支气管腔内壁及腔内病变的表现。ＣＴＶＢ可以到达一般纤维支气管镜所不能到达的第Ｖ 级支气管并可以越过阻塞部位对远端的支气管进行观察。结论 螺旋ＣＴ 仿真支气管镜可以较真实地反映复杂气道的解剖关系及气道的形态改变，为临床提供了一种新的无创的诊断方法。
Purpose To investigate the clinical applications of helical CT virtual bronchoscopy (CTVB).Methods 25 patients underwent CTVB and 22 of them were submitted both to CTVB and fiberoptic bronchoscopy (FOB).Did comparative study on the two bronchoscopic findings.Results The inner surface of airway and endoluminal findings on CTVB were similar to those of FOB while CTVB was able to visualize areas beyond stenosis and reached brochi up to the fifth order.FOB could not.Conclusion CTVB can illustrate complicated anatomical relation and evaluate the lesion of airway.CTVB provides a new noninvasive diagnostic method for clinical examination.
