Two thousand carotid arteries were evaluated by B-mode real-time ultrasound, Doppler ultrasound, carotid phonoangiography, and oculoplethysmography. All patients were referred for evaluation of asymptomatic bruits, transient ischemic attacks, or stroke. Angiography was performed on 760 vessels and operative intervention upon 248 arteries. B-mode correctly identified 123/126 vessels said to be normal by angiography; it identified nonstenotic plaques in 296 vessels where angiography only noted 288 instances of nonstenotic plaque. In 341/346 vessels, lesions greater than 50 per cent stenosis were correctly identified by B-mode. Compared with angiography, B-mode ultrasound has a sensitivity of 98.5 per cent for greater than 50 per cent stenosis and a specificity of 100 per cent. For lesions less than 50 per cent stenotic, B-mode has a sensitivity of 100 per cent, a specificity of 98.3 per cent, and a calculated accuracy of 98.9 per cent.
采用B型实时超声、多普勒超声、颈动脉血管造影术和眼体积描记法对2000条颈动脉进行了评估。所有患者均因无症状性杂音、短暂性脑缺血发作或中风前来接受评估。对760条血管进行了血管造影，并对248条动脉进行了手术干预。B型超声正确识别出血管造影显示正常的126条血管中的123条；它在296条血管中识别出非狭窄性斑块，而血管造影仅发现288例非狭窄性斑块。在346条血管中的341条中，B型超声正确识别出狭窄程度大于50%的病变。与血管造影相比，B型超声对狭窄程度大于50%的病变敏感性为98.5%，特异性为100%。对于狭窄程度小于50%的病变，B型超声敏感性为100%，特异性为98.3%，计算准确率为98.9%。
