Virtual endoscopy (VE) of the nasal cavity and paranasal sinuses is a new and noninvasive imaging tool. Three-dimensional visualization via VE has been applied to display endoluminal pathology in the colon, trachea, bronchial tree, vessels, urinary tract, and paranasal sinuses. Postprocessing of raw data acquired from helical computed tomography with advanced software can formulate a virtual three-dimensional model by a volume rendering technique. VE permits dynamic navigation within a lumen using a "fly-through" feature. Applications of this investigative modality in the nasal cavity and paranasal sinuses complement conventional fibre-optic rhinoscopy in diagnosis, operative planning, and the education of trainees.
鼻腔和鼻窦的虚拟内镜检查（VE）是一种新的、非侵入性的成像工具。VE 的三维可视化已应用于显示结肠、气管、支气管树、血管、尿路和鼻窦的腔内病理学。通过先进的软件对螺旋 CT 采集的原始数据进行后处理，可以通过体绘制技术构建一个虚拟的三维模型。VE 通过“飞行通过”功能允许在管腔内进行动态导航。这种检查方式在鼻腔和鼻窦中的应用补充了传统的纤维光学鼻内镜检查在诊断、手术计划和培训生教育方面的作用。
