Advances in computer technology have permitted development of virtual reality images of the tracheobronchial tree using data sets derived from helical CT of the chest. To determine the relevance of these images to actual bronchoscopic findings, we compared "virtual bronchoscopy" images with videotaped bronchoscopy results in 20 patients who had undergone both helical chest CT and fiberoptic bronchoscopy during clinical evaluation of their thoracic problems. Suboptimal endobronchial simulations in ten patients identified important, readily-addressed technical requirements for this imaging procedure. In the ten patients with technically suitable renderings of the airway, virtual bronchoscopy simulations accurately demonstrated endobronchial obstructions by tumor in five, airway distortion and/or ectasia in four, and accessory bronchi in another. These preliminary observations suggest that virtual bronchoscopy simulations accurately represent major endobronchial anatomic findings. This technique may have a role in prebronchoscopy planning, endoscopy training, and/or endobronchial therapy, and merits further study.
计算机技术的进步使得利用胸部螺旋CT获得的数据集来开发气管支气管树的虚拟现实图像成为可能。为了确定这些图像与实际支气管镜检查结果的相关性，我们将20例在胸部疾病临床评估期间同时接受了胸部螺旋CT和纤维支气管镜检查的患者的“虚拟支气管镜检查”图像与录像支气管镜检查结果进行了比较。10例患者的支气管内模拟效果欠佳，确定了该成像程序的重要且易于解决的技术要求。在10例气道渲染技术合适的患者中，虚拟支气管镜检查模拟准确显示了5例肿瘤导致的支气管内阻塞、4例气道扭曲和/或扩张以及另外1例副支气管。这些初步观察结果表明，虚拟支气管镜检查模拟准确地呈现了主要的支气管内解剖学发现。这项技术可能在支气管镜检查前规划、内镜培训和/或支气管内治疗中发挥作用，值得进一步研究。
