通过动脉造影和2mhz脉冲超声多普勒检查显示42条颅内颈内动脉。利用频谱分析研究眼睑后5 ~ 7cm深度的颅内颈内动脉多普勒信号。制定了狭窄的标准，并制定了避免与附带效应混淆的方法。在动脉造影显示的33个颅内ica中，22个正常，无狭窄，11个显示不同程度的狭窄，范围从20%到75%。另有7例完全闭塞。狭窄的多普勒标准代表频率升高和对称突出低频（SPLF）被利用，并从附带影响中分离出来，提供88%的总体准确性，95%的特异性和73%的灵敏度。这项技术看来很有前途，值得进一步开发和利用。
Forty-two intracranial internal carotid arteries were visualized by both arteriography and 2 MHz pulse ultrasonic Doppler examinations. The intracranial internal carotid artery Doppler signals were studied at 5-7 cm depth behind the eyelid using frequency spectral analysis. Stenosis criteria were developed and methods of avoiding confusion with collateral effects devised. Among 33 intracranial ICAs visualized on the arteriograms, 22 were normal without stenosis and 11 displayed some degree of stenosis ranging from 20 to 75 percent. An additional 7 were totally occluded. Doppler criteria of stenosis representing elevated frequencies and symmetrical prominent low frequencies (SPLF) were utilized and separated from collateral effects to provide an overall accuracy of the technique of 88 percent with a 95 percent specificity and a 73 percent sensitivity. The technique appears sufficiently promising to justify further development and utilization.
