摘　　要：目的:探讨CT仿真支气管内窥镜(CTVB)的临床应用价值及限度。方法:用螺旋CT对50例患者行容积扫描,通过计算机后处理功能,进行气管、支气管内表面成像。结果:CTVB对12级支气管显示率100％,3级支气管显示率79.8％,4级支气管显示率36.3％,5级支气管显示率9.5％。CTVB对腔内病变敏感性较高,但特异性较低。结论:CTVB是一种无创的检查方法,是纤维支气管镜的补充检查手段,具有一定的应用潜力,值得临床上进一步推广应用。Objective: To investigate the clinical value of CT virtual bronchoscopy (CTVB). Methods: Fifty patients with clinically suspected lung diseases were examined with helical CT. The raw data were downloaded to a workstation for interactive intraluminal. Results: 47 lesions were identified on the CTVB including 38 cases of lung cancer, 7 of lung tuberculosis, 2 of inflammary process. Another three were found nothing wrong. The sensitivity of CTVB to display the intraluminal lesions was good, but the specificity was not good enough. Conclusion: CTVB is a nonivasive diagnostic method and could be a effective tool in the detection of bronchus lesions.
