【摘要】 目的 :评价螺旋CT仿真支气管镜 (CTVB)在中央型肺癌诊断中的应用价值。方法 :3 6例中央型肺癌患者行螺旋CT容积扫描 ,将数据重建获得CT仿真支气管镜图像 ,并对CTVB图像进行分析。结果 :CTVB显示 10 0 %的段以上支气管和 45 %的亚段支气管 ,并可显示支气管腔内壁、腔内病变 ,肿瘤呈结节状隆起 ,表面光滑 ,还能显示支气管梗阻远端的情况。结论 :CTVB是一种无创性观察气管、支气管的方法 ,酷似纤维支气管镜 ,是中央型肺癌诸多检查方法的一种极好补充。更多还原

【Abstract】 Objective:To evaluate the clinical application of CT virtual bronchoscopy (CTVB) in the diagnosis of central lung cancer.Methods:Thirty six cases with central lung cancer underwent volume scanning using spiral CT.The virtual bronchoscopy pictures were obtained by the workstation.Results:CTVB could reveal 100% segmental bronchus and 45% subsegmental bronchus.CTVB showed can show the innev wall of dronchus and trachea and tumor in the lumen,the tumor appeared as nodules with smooth surface.CTVB was better in revealing the distal segment of bronchial obstruction.Conclusion:CTVB is a noninvasive method of observing the airway.It simulates the images observed under fiberoptic bronchoscopy.It is complementary in examing central lung cancer.更多还原
