A prospective trial was set up in 100 patients, who underwent arteriography of the cerebropetal and cerebral arteries, to determine the value of the direct examination of the Carotid arteries using a continuous wave bidirectionnal Doppler with spectrum frequency analysis. The results of this non-invasive direct technique are compared with the biplane arteriography and with the indirect noninvasive oculoplethysmography (OPG-Gee). The conclusions of this study are that the direct Doppler examination with spectrum frequency-analysis is a very good tool in detecting lesions in the Carotid arteries, and is superior to the indirect OPG-Gee examination, especially in stenoses of 30-69%.
对100例患者进行了一项前瞻性试验，这些患者接受了向心性脑动脉和脑动脉造影，以确定使用具有频谱频率分析功能的连续波双向多普勒直接检查颈动脉的价值。将这种非侵入性直接技术的结果与双平面动脉造影和间接非侵入性眼体积描记法（OPG-Gee）进行比较。这项研究的结论是，采用频谱频率分析的直接多普勒检查是检测颈动脉病变的一种非常好的工具，并且优于间接OPG-Gee检查，尤其是在30%-69%的狭窄病例中。
