One hundred patients with suspected cerebrovascular disease were studied, using Doppler imaging techniques (Dop-Scan), as described by Spencer in 1974. Using a continuous wave Doppler probe, derived images of the carotid vessels and their tributaries were constructed. Twenty-nine of these patients had angiographic studies. A close correlation between Doppler imaging and angiography was found. Although the imaging of the bifurcations does provide useful clinical information compatible to information obtained at angiography, it is necessary to supplement this by analyzing the Doppler signals generated at defined segments of the circulation. Some of the pitfalls of Doppler diagnosis of extracranial vascular disease have been avoided by the dual techniques of imaging and analyzing the Doppler signals directly over the neck vessels. Doppler imaging techniques allow safe, inexpensive, noninvasive studies which are reproducible and reliable. The techniques are easily adaptable to office and hospital practice and have the distinct advantage of saving some patients from angiographic investigation.
对100例疑似脑血管疾病的患者进行了研究，采用了1974年斯宾塞所描述的多普勒成像技术（Dop - Scan）。使用连续波多普勒探头构建了颈动脉及其分支的衍生图像。其中29例患者进行了血管造影研究。发现多普勒成像与血管造影之间存在密切相关性。虽然分叉处的成像确实提供了与血管造影获得的信息相兼容的有用临床信息，但有必要通过分析循环特定节段产生的多普勒信号来补充这一点。通过对颈部血管直接进行成像和分析多普勒信号的双重技术，避免了一些颅外血管疾病多普勒诊断的陷阱。多普勒成像技术允许进行安全、廉价、无创的研究，这些研究具有可重复性和可靠性。这些技术很容易应用于门诊和医院实践，并且具有使一些患者免于血管造影检查的明显优势。
