title: [High frequency color duplex sonography in cervical spondylosis].
abstract: OBJECTIVE
  To observe the morphological structure and hemodynamic changes of the vertebral artery in cervical spondylosis by high frequency color duplex sonography.
  
  
  METHODS
  We measured 138 cases of cervical spondylosis at the vertebral artery with a 7.5-10 MHz probe of high frequency color duplex sonography, to determine morphological changes, Diameter(D), Velocity(V), Blood flow volume, and Resistance index(RI) and (PI). A controlled analysis was performed at the same time.
  
  
  RESULTS
  The measurement showed that the vertebral arteries of the patients bent more severely than the controlled group. There was a significant difference between the two groups (P < 0.01) in Diameter (D), Velocity (except mean velocity), Blood flow volume, and resistance index (RI) and (PI).
  
  
  CONCLUSIONS
  High frequency color duplex sonography has provided clinical judement on morphological and blood flow dynamic parameter changes of the vertebral artery with a valuable objective basis.
