The reliability of the echo-Doppler (duplex) system for the visualization of the vertebral arteries was evaluated in 304 patients, in which 588 vertebral arteries had been investigated. Of these, 545 (92.69 per cent) arteries, either normal or diseased, were successfully visualized. However, the origin of the vertebral artery from the subclavian artery was localized in only 354 vessels (60 per cent of those visualized). Angiography was available for comparison in 33 arteries. The overall accuracy and the sensitivity of the duplex were 63.64 per cent and 38.46 per cent, respectively; they attained 86.67 per cent and 83.33 per cent in the vertebral arteries visualized from their origin, (a site early and most commonly involved by the atherosclerotic process). As the vertebral arteries can be visualized with a 92 per cent success rate, their examination should become a routine part of the duplex cerebrovascular study. In order to accurately detect diseased vertebral arteries, their origin from the subclavian artery should be localized.
对304例患者进行了评估，以检测回声多普勒（双功能）系统对椎动脉成像的可靠性，这些患者中共检测了588条椎动脉。其中，545条（92.69%）动脉，无论正常与否，均成功成像。然而，仅在354条血管（占成像血管的60%）中确定了椎动脉起自锁骨下动脉。有33条动脉可进行血管造影以作对比。双功能超声的总体准确率和敏感性分别为63.64%和38.46%；在从起源处（动脉粥样硬化过程早期最常累及的部位）成像的椎动脉中，准确率和敏感性分别达到86.67%和83.33%。由于椎动脉成像成功率可达92%，对其检查应成为双功能脑血管检查的常规部分。为准确检测病变椎动脉，应确定其起自锁骨下动脉的位置。
