title: [Anatomy structures of nasal cavity and paranasal sinus on virtual endoscopy and coronal image].
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 by coronal scanning image. To some extent, bony anatomy was clearer.
  
  
  CONCLUSIONS
  Virtual endoscopy is of value in realizing characteristics of nasal cavity and paranasal sinus anatomy.
