Noninvasive diagnosis of vertebral artery disease is difficult, but the combined use of Doppler ultrasonography and dynamic radionuclide studies, with measurement of the carotid-basilar delay (CBD), increases the sensitivity and can indicate the level (cervical or distal) of the lesion. Forty patients with cerebrovascular disease were studied by continuous wave Doppler and CBD and the results were compared with vertebral angiograms. The mean normal CBD value was determined for a control group of 18 patients. Sensitivity and specificity were 87.5 per cent and 75 per cent, respectively, for Doppler alone, and 100 per cent and 60 per cent for combined Doppler and CBD.
椎动脉疾病的无创诊断较为困难，但联合使用多普勒超声检查和动态放射性核素研究，并测量颈基底延迟（CBD），可提高敏感性并能指示病变的部位（颈部或远端）。对40例脑血管疾病患者进行了连续波多普勒和CBD研究，并将结果与椎动脉血管造影进行了比较。测定了18例对照组患者的平均正常CBD值。单独使用多普勒时，敏感性和特异性分别为87.5%和75%，联合使用多普勒和CBD时，敏感性和特异性分别为100%和60%。
