The findings of color Doppler flow imaging of the extracranial cerebral arteries in 75 patients were compared with i.a. DSA. Carotid stenoses greater than 50% and carotid occlusions were shown by sonography with a sensitivity of 91% and a specificity of 97%. The severity of the stenosis was in agreement in 88% of cases using the two methods. Sonography of the vertebral arteries achieved a sensitivity of only 65% and a specificity of 88%. Sonographic examination of the ophthalmic artery in order to demonstrate carotid stenosis achieved a sensitivity of only 29% and provided no additional information. Retrobulbar kinking of the ophthalmic artery was found in 30/178 vessels and may be a cause of misinterpretation.
对75例患者的颅外脑动脉进行彩色多普勒血流成像检查，并与数字减影血管造影（DSA）等检查结果进行比较。超声检查显示，颈动脉狭窄大于50%和颈动脉闭塞的敏感性为91%，特异性为97%。两种方法对狭窄严重程度的判断在88%的病例中一致。椎动脉超声检查的敏感性仅为65%，特异性为88%。为显示颈动脉狭窄而对眼动脉进行超声检查的敏感性仅为29%，且未提供额外信息。在178条血管中发现30条眼动脉球后扭结，这可能是造成误诊的原因。
