The purpose of this study was to determine the feasibility of using virtual bronchoscopy simulations to depict stenoses of the tracheobronchial tree. Virtual bronchoscopy simulations, based on ray casting, were applied to spiral-CT data sets of 29 patients presenting 41 stenoses of the central airways, proved with fiberoptic bronchoscopy. Simulations of the inner walls of the airways were of good quality in 27 of 29 patients. Airway stenoses were depicted in 39 of 41 cases. Evaluation of the length of stenoses and surrounding tissues required simultaneous display of multiplanar reformations. Virtual bronchoscopy provides a valuable road map for bronchoscopy, in an image format familiar to bronchoscopists.
本研究的目的是确定使用虚拟支气管镜模拟来描绘气管支气管树狭窄的可行性。基于光线投射的虚拟支气管镜模拟应用于29例经纤维支气管镜证实存在41处中央气道狭窄的患者的螺旋CT数据集。29例患者中有27例气道内壁模拟质量良好。41例中有39例描绘出气道狭窄。评估狭窄长度和周围组织需要同时显示多平面重建图像。虚拟支气管镜以支气管镜检查人员熟悉的图像形式为支气管镜检查提供了有价值的路线图。
