双工超声扫描仪将实时B型成像与单门可变范围脉冲多普勒相结合。颈动脉粥样硬化程度的检测和分类是通过对从感兴趣的血管获得的脉冲多普勒速度信号进行频谱分析来实现的。对1978年1月至1980年1月期间750例疑似颈动脉颅外段病变的患者进行了评估。其中135名患者(18%)接受了颈动脉分叉双平面的脑动脉造影术。这个。这些患者的狭窄程度是独立测量的，并可与双工扫描和频谱分析的结果进行比较。在所研究的259条颈动脉中，有252条(97%)双工扫描正确地检测到了疾病的存在。受累程度不一，从直径缩小小于10%的斑块到导致完全闭塞的斑块。对于直径缩小小于10%的病变，该技术的准确性较低。
The duplex ultrasonic scanner combines real-time B-mode imaging with a single-gate, variable- range pulsed Doppler. The detection and categori.zation of the severity of carotid artery atherosclerosis is achieved by performing spectral analysis of the pulsed Doppler velocity signal obtained from vessels of interest. Using this technique, 750 patients with suspected extracranial carotid artery disease were evaluated between January 1978 and January 1980. One hundred thirty-five of these 750 patients (18%) underwent cerebral arteriography performed with biplanar views of the carotid bifurcation. The. degree of stenosis was measured independently in these patients and was available for comparison with the results of duplex scanning and spectral analysis.Duplex scanning correctly detected the presence of disease in 252 of 259 carotid arteries studied (97%). The extent of involvement varied from plaques that produced less than 10% diameter reduction to those that resulted in a total occlusion. The technique was less accurate with lesions that produced less than 10% diameter reduction.
