应用颈椎横突孔ＣＴ扫描和高刺激率ＡＢＲ测试，检查１８例椎基底动脉缺血性眩晕 （ＶＢＴＩＶ）患者，结果发现两种检查方法的阳性率是一致的（７２．２％。８３．３％，Ｐ＞０．０５）。提示：高刺 激率ＡＢＲ诊断ＶＢＴＩＶ有形态学依据，与颈椎横突孔ＣＴ扫描联合应用，有助于提高客观诊断ＶＢ－ ＴＩＶ的可靠性。
18 cases of vertebrobasilar ischemic vertigo (VBTIV) were examined by transverse cervical CT scan and high-rate ABR test. The positive rates of the two methods were consistent (72.2%, 83.3% %, P> 0.05). It is suggested that the diagnosis of VBTIV with high stimulation rate ABR has morphological basis and combined with CT scan of cervical transverse foramen, which helps to improve the reliability of objective diagnosis of VB-TIV.
