title: Relationship of the changes of cervical MRI, TCD and BAEP in patients with "isolated" vertigo.
abstract: OBJECTIVE
  To study the relationship and changes of cervical MRI, TCD and BAEP in patients with "isolated" vertigo.
  
  
  METHODS
  The relationship and changes of cervical MRI, TCD and BAEP were investigated respectively in 125 patients with "isolated" vertigo and 100 healthy controls.
  
  
  RESULTS
  There were statistically significant differences between two groups for overall abnormalities of TCD (X(2) = 61.96, P<0.01), BAEP (X(2) = 97.99, P<0.01), and cervical MRI severity scale (Z = -8.71, P<0.01). In vertigo group, results showed significant correlations between TCD and cervical MRI, TCD and BAEP as well. And analysis on TCD PI and some items of BAEP demonstrated positive linear correlations. There were no statistical differences or correlations in control group.
  
  
  CONCLUSIONS
  TCD is a sensitive method of "isolated" vertigo screening. A combined test protocol of cervical MRI, TCD and BAEP has superiorities to assess "isolated" vertigo.
