摘　　要：目的　评价 CT仿真支气管内窥镜 (VB)成像方法及临床应用。　方法　对 5 0例 CTVB检查经纤维支气管镜或病理证实的患者进行分析。中心型肺癌 2 7例 ,肺癌术后 4例 ,支气管憩室 1例 ,正常支气管 18例。将螺旋 CT扫描数据传至 Ad-vantage Windows 3.1版本工作站 (GE Medical Systems) ,用 Smooth Navigator软件功能建成 CTVB图像进行分析。　结果　CTVB能 10 0 %地观察到段以上支气管和 80 %以上亚段支气管。 2 7例中心型肺癌发现支气管狭窄 2 3处 ,闭塞 4处 ,肺癌术后支气管残端 4处 ,右中间段支气管憩室 1例。　结论　 CTVB是一种极其优越的无创性观察支气管腔的方法 ,与纤维支气管镜相比 ,有其优点和限度。分析图像时结合原始图像和 MPR图像 ,则可提供腔壁和腔外的更多信息。Objictive To evaluate the clinical application of CT virtual bronchoscopy(VB) in bronchial pulmonary diseases. Methods Fifty cases were studied with CTVB. All patients were proved with fiberoptic bronchoscopy or pathology.Among the 50 cases lung cancer of center type( n =27),post operative lung cancer ( n =4),bronchial diverticulum ( n =1),normal bronchus( n =18).CTVB was performed using navigator smooth software on the workstation(Advantege Windows 3.1 GE Medical Systems). Results CTVB could reveal 100% segmental bronchus and more than 80% subsegmental bronchus mimicing fiberoptic bronchoscopy. Bronchial stenosis ( n =23) and occlusion (n =4)due to tumors. Post operative bronchial stump( n =4) appeared as smooth blind end without recurrence of tumors as confirmed by fiberoptic endoscopy. Conclusion CTVB is a new method of noninvasive bronchial pulmonary diseases. Comparing with fiberoptic bronchoscopy, CTVB possess incomparable advantages. However CTVB can not replace conventional bronchoscopy for demonstrating mucosal abnormalities and for obtaining histolo gic samples.
