Three hundred and forty-six carotid arteries were examined with a two-dimensional 3.5 MHz real time scanner in 173 patients with evidence of cerebral ischaemia; 62 carotid arteries were investigated by selective trans-femoral angiography in 36 of these patients at the same time. Sonography and angiography agreed in 20 (91%) of 22 angiographically normal cases, in all cases (10) with haemodynamically insignificant plaques, in eight (66%) of 12 stenosis of less than 50%, in nine (90%) of ten stenosis of more than 50% and in four (44%) of nine total occlusions. Sensitivity of carotid sonography varied with the severity of the lesion from 44 to 100%. Its specificity was 91%. B-scan sonography of the carotid artery, in the presence of cerebro-vascular lesions (transitory ischaemia, cerebral infarcts) and in the presence of non-specific symptoms and of asymptomatic vascular murmurs, may provide indications for the use of angiography. Its values as a screening procedure remains to be assessed.
采用二维3.5兆赫实时扫描仪对173例有脑缺血证据的患者的346条颈动脉进行了检查；同时对其中36例患者的62条颈动脉进行了选择性经股动脉血管造影。超声检查与血管造影在22例血管造影正常的病例中有20例（91%）结果一致，在所有有血流动力学意义不明显斑块的病例（10例）中结果一致，在12例狭窄小于50%的病例中有8例（66%）结果一致，在10例狭窄大于50%的病例中有9例（90%）结果一致，在9例完全闭塞的病例中有4例（44%）结果一致。颈动脉超声检查的敏感性随病变严重程度不同而在44%至100%之间变化。其特异性为91%。在存在脑血管病变（短暂性脑缺血、脑梗死）以及存在非特异性症状和无症状血管杂音的情况下，颈动脉B型超声检查可为血管造影的应用提供指征。其作为一种筛查方法的价值仍有待评估。
