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%.
