Title: Anatomy Structures of Nasal Cavity and Paranasal Sinus on Virtual Endoscopy
Abstract: Objective To evaluate normal and bony anatomy of nasal cavity and paranasal sinus on the spiral CT virtual endoscopy(VE) and coronal scanning image. Methods 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. Results Turbinates, meatus and ostium meatal complex were better viewed by virtual endoscopy compared with coronal scanning image. To some extent, bony anatomy were better clearly. Conclusion Virtual endoscopy is of value and help to realize characteristics of nasal cavity and paranasal sinus anatomy.
