摘要
目的 探讨SPECT、TCD及BAEP对椎基底动脉缺血性眩晕 (VBAIV)的诊断价值。方法 对 10 0例临床诊断为VBAIV患者进行SPECT、BAEP、TCD检查 ,并对其检查的结果进行分析、对比。结果 10 0例中SPECT的阳性率为 87 0 % ,BAEP为 5 8 3% ,TCD为 78 0 %。结论 SPECT的阳性率最高 ,能较灵敏地直接反映脑缺血的部位 ;BAEP阳性率最低 ,但能较正确的反映出脑干缺血的依据 ;TCD检查简单、方便 ,对脑血管和脑血流状态反映较灵敏 ,但定位准确性较差。三者在该病的诊断中均可提供有价值的客观依据 ,且有互相补充的作用。
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
