Directional continuous wave Doppler ultrasonography has been used to assess the extracranial carotid arteries of over 500 patients, 90 of whom have had angiography performed. The angiographic and Doppler findings are compared, showing that this simple ultrasound technique is able to detect carotid stenosis and occlusion, but is unreliable in the detection of mild atheromatous change. In this series, the method detected 90% of the angiographically proven carotid stenoses, being considerably more accurate than routine auscultation. It would seem that continuous wave ultrasonography is a safe and practical screening test in those patients in whom arteriography is being considered.
定向连续波多普勒超声检查已用于评估500多名患者的颅外颈动脉，其中90名患者已接受血管造影。对血管造影和多普勒检查结果进行了比较，结果表明这种简单的超声技术能够检测出颈动脉狭窄和闭塞，但在检测轻度动脉粥样硬化改变方面并不可靠。在本系列研究中，该方法检测出血管造影证实的颈动脉狭窄患者中的90%，比常规听诊准确得多。对于那些正在考虑进行动脉造影的患者，连续波超声检查似乎是一种安全实用的筛查方法。
