摘　　要：目的 以纤维支气管镜检查(FB)作对比,评价CT仿真支气管镜(CTVB)的临床应用价值。方法 85例符合做纤维支气管镜检查指征的患者,先行CT仿真支气管镜的检查,再做纤维支气管镜的检查。以纤维支气管镜检查为金标准评价CT仿真支气管镜的诊断率。结果 设定纤维支气管镜检查的诊断率为100％,以此为对照,CT仿真支气管镜对全部病灶诊断率为84.71％,对主气管病灶诊断率为100％,对1级支气管病灶诊断率为100％,对2级支气管病灶诊断率为91.30％,对3级支气管病灶诊断率为59.09％。结论 病灶发生在1,2级支气管上,CT仿真支气管镜与纤维支气管镜检查的检出率和诊断率基本一致,病灶发生在3级及3级以下的支气管上,CT仿真支气管镜与纤维支气管镜检查的诊断率有较明显的差异。CT仿真支气管镜对病灶发生在2级及2级以上的支气管病灶诊断基本可靠,CT仿真支气管镜对病灶发生在3级及3级以下的支气管病灶诊断不可靠。Objective To evaluate clinical application of CT virtual bronchoscopy (CTVB) by comparing with the fiberoptic bron-choscopy(FB). Methods 85 patients with the indication of FB accepted the examination of CTVB before FB. Then further evaluate the diagnostic rate of CTVB through comparing the 'golden standard' of FB. Results Given the accurate rate of FB in detecting all lesions as 100%, the accurate rate of CTVB is 84.71%. The accurate rate of detecting lesions located in trachea and primary bronchi are all 100% and accurate rate will decline to 91.30% and59.09% respectively when lesions in lobetal and subsegmental bronchi. Conclusion The diagnostic accuracy rate of CTVB in detecting lesions in primary and secondary bronchi are same as that of FB. but the accurate rate of CTVB in segmental and subsegmental bronchi are in great significance with FB. The application of CTVB in finding lesions in primary and secondary bronchi is dependable and relative unreliable in segmental and subsegmental bronchi.
