The sophistication of three-dimensional (3-D) radiographic imaging from CT data has accelerated with the development and ongoing advances of helical CT. Virtual bronchoscopy (VB), the ability to create 3-D models of the airways and navigate through the tracheobronchial tree lumen in realtime simulated bronchoscopy, has gained popularity over the past 3 years. The ability of VB to image the airway and mediastinal structures simultaneously and in a 3-D format has helped revolutionize CT imaging. Unlike conventional bronchoscopy, VB can display the extent of narrowing caused by an airway lesion, the presence of patentcy beyond a stenosis, and the relationship between an airway lesion and the adjacent mediastinal structures.
随着螺旋CT的发展和不断进步，基于CT数据的三维（3-D）放射成像技术日益成熟。虚拟支气管镜检查（VB），即能够创建气道的三维模型并在实时模拟支气管镜检查中穿过气管支气管树管腔的技术，在过去3年中越来越受欢迎。VB以三维格式同时成像气道和纵隔结构的能力，推动了CT成像的变革。与传统支气管镜检查不同，VB可以显示气道病变导致的狭窄程度、狭窄远端的通畅情况，以及气道病变与相邻纵隔结构之间的关系。
