Diagnostic value of SPECT,TCD and BAEP to vertebral-basilar artery ischemia vertigo / 临床神经病学杂志

ABSTRACT

Objective To investigate the diagnostic value of SPECT,TCD and BAEP to vertebral basilar artery ischemia vertigo Methods 100 cases of vertebral basilar artery ischemia vertigo were inspected by SPECT,BAEP and TCD All the results were analyzed and compared Results Among 100 cases, it shows that the diagnostic rate of SPECT is 80 percent,BAEP is 58 3 percent and TCD is 78 percent Conclusion SPECT is found having the highest diagnostic rate,it sensitively and accurately reflects the position of cerebral ischemia Although BAEP having the lowest diagnostic rate, it can still effectively shows Brain Stem Ischemia Comparing with SPECT and BAEP, TCD is simple and convenient to carry out It sensitively reflects the conditions of cerebral vessel and cerebral blood stream,but it is insensitive to make sure the position Therefore, three of them offer the valuable,external and diagnostic proof to vertebral basilar artery ischemia vertigo,and they can have a role of inter reinforce
