title: [The diagnostic value of multi-planar reconstruction in semicircular canals disease by HRCT].
abstract: OBJECTIVE
  To study the diagnostic value of high-resolution computed tomography (HRCT) and multiplanar reconstruction (MPR) in assessment of semicircular canals disease.
  
  
  METHODS
  Eighty-three patients were scanned with HRCT and the original data were processed with MPR. The semicircular canals full length was respectively observed in one image of MPR in the normal ears. The abnormal location of the canal were observed.
  
  
  RESULTS
  In one image the full length of the horizontal, superior and posterior semicircular canal can be respectively displayed in one image of MPR in normal ears. By this way ,1 superior semicircular canal dehiscence (SSCD)was found in precaution group, 1 superior and 2 horizontal semicircular canal blocked, 1 vestibular aqueduct (VA) joined into superior semicircular canal and 2 VAs joined into posterior semicircular canal and abnormity of the three semicircular canals were found in SNHL.
  
  
  CONCLUSIONS
  MPR canould display the three canals full length in one picture and have a high specificity in the diagnosis of the semicircular canal abnormity.
