To evaluate normal and bony anatomy of nasal cavity and paranasal sinus on the spiral CT virtual endoscopy(VE) and coronal scanning image.
After patients were scanned on axial or coronal position by spiral CT, data were transferred to workstation. Structures such as ostium-meatal complex(OMC) were viewed by navigator software when threshold was changing.
Turbinates, meatus and ostium-meatal complex were better viewed by virtual endoscopy compared with by coronal scanning image. To some extent, bony anatomy was clearer.
Virtual endoscopy is of value in realizing characteristics of nasal cavity and paranasal sinus anatomy.
通过螺旋CT虚拟内镜（VE）及冠状位扫描图像评估鼻腔及鼻窦的正常及骨质解剖结构。
患者经螺旋CT进行轴位或冠状位扫描后，将数据传输至工作站。通过导航软件在阈值变化时观察诸如窦口鼻道复合体（OMC）等结构。
与冠状位扫描图像相比，虚拟内镜能更好地显示鼻甲、鼻道及窦口鼻道复合体。在一定程度上，骨质解剖结构更清晰。
虚拟内镜在认识鼻腔及鼻窦解剖结构特点方面具有价值。
