摘要
目的 :评价螺旋CT仿真支气管内窥镜 (CTVB)临床应用价值。材料和方法 :对 5 2例气管、支气管行螺旋CT(GEHiSpeedAdvantageCT/i)扫描 ,将其数据传至AdvantageWindows 3 .1版本工作站 ,用NavigatorSmooth软件建成酷似纤维支气管镜所见的CTVB图像 ,并与纤维支气管镜对照。其中 4例与病理标本对照。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例 ,闭塞 4例 ,肺癌术后支气管残端 4例 ,气管狭窄 2例 ,右中间段支气管憩室 1例。结论 :CTVB是一种新的无创性观察气管、支气管腔的方法 ,酷似纤维支气管镜所见 。
Purpose: To evaluate imaging methods and clinical application of CT virtual bronchoscopy (VB). Meterials and Methods: Fifty two cases were performed by using spiral CT (Hispeed Advantage CT/i), the data were transferred to computer workstation (Advantage Windows 3.1). The CTVB images were generated from using Navigator Smooth soft ware and compared with fiberoptic bronchoscopy. 4 cases of them were correlated with pathologic samples. Results: CTVB could reveal 100% segmental bronchi and more than 80% subsegmental bronchi mimicking fiberoptic bronchoscopy. Among the 27 patients with lung cancer of center type, bronchial stenosis (n=23) and occlusions (n=4) were due to masses. Post operated residual bronchial stumps (n=4) showed smooth blinds. One case exhibited the bronchial diverticulum in the right bronchus. Conclusions: CTVB provided a noninvasive fiberoptic bronchoscopelike image, but it can not replace fiberoptic endoscopy for demonstrating mucosal abnormalities and for obtaining histologic samples.
