摘　　要：目的 :研究肺癌CT仿真支气管内窥镜 (CTVB)表现及临床意义。方法 :30例肺癌患者行螺旋CT薄层扫描 ,将重建后的扫描数据传输至同机工作站 ,利用机内图像分析软件形成CTVB图像。结果 :CTVB共显示气管支气管病变 5 9处 ,主要病理改变为管腔闭塞 (15处 ) ,管腔狭窄 (9处 ) ,管壁不规则、僵硬 (5处 ) ,外压性改变 (6处 ) ,管腔内肿物 (6处 ) ,管腔内水肿及炎性分泌物 (14处 ) ,肺癌术后支气管残端 (4处 )。结论 :CTVB作为一种无创检查方法 ,可显示气管支气管多种病理改变 ,合理选取CT阈值可提高CTVB的鉴别诊断能力。Objective:To study the manifestations of pulmonary carcinoma in CT virtual bronchoscopy (CTVB) and investigate the relevant clinical significance.Methods:Thirty patients with pulmonary carcinoma were examined with thin-slice helical CT scaning.The reconstructed imaging data was transferred to the workstation (GE Advantage Windows 3.1) and the CTVB images were obtained by using imaging analytic soft-ware. 5'HZResults:Thirty cases with pulmonary carcinoma included 17 of central type,6 of peripheral type,3 of metastatic type and 4 of post-operation type.With CTVB altogether 59 sites of pathological lesion were revealed,including bronchial occlusion(n=15),bronchial stenosis(n=9),irregular bronchial wall(n=5),external compression(n=6),intraluminal tumour(n=6),intraluminal edema and secretion(n=14) and bronchial stump of post-operation(n=4).Conclusion:As a new and noninvasive technique CTVB may display many tracheobronchial pathological changes.Adjusting CT threshold value reasonably may improve its sensitivity in differential diagnosis.
