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. METHOD: 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. RESULT: 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. CONCLUSION: Virtual endoscopy is of value in realizing characteristics of nasal cavity and paranasal sinus anatomy.
