AB  - OBJECTIVE: Compare various Doppler methods for the quantification of the degree 
      of stenosis on 85 patients. METHOD: the following parameters were measured: 
      maximal velocity (Vmax) inside the stenosis (PW), grades of spectral disturbances 
      at the outlet of the stenosis (PW-CW), index of spectral disturbance (STI) at the 
      outlet of the stenosis (PW-CW), ratio of velocities I(IC/CC) in internal and 
      common carotid (PW), ratio of vessel cross section and residual lumen area (% 
      STEN) by color Doppler. The reference method was the Grades of spectral 
      disturbance and the index of stenosis measured post stenosis. (Method validated 
      against angiography and pieces of endarterectomy.) The following comparisons were 
      done; grades and STI by CW against grades and STI by PW, Vmax (PW) against grade 
      and STI, % STEN (color) against grade and STI, % STEN (color) against Vmax (PW), 
      I(IC/CC) (PW) against grade and STI, I(IC/CC) (PW) against Vmax. CONCLUSION: (a) 
      grades or stenosis index : showed the best reproductibility; (b) a high 
      correlation was found between the grades or stenosis index post stenosis measured 
      by CW or PW; (c) Vmax was not proportional to the stenosis degree and showed 
      large fluctuations for the same stenosis degree; (d) the I(IC/CC) showed large 
      fluctuations for the same stenosis degree, the correlation was poor for this 
      velocity ratio. Both Vmax and I(IC/CC) allow to detect only 2 groups of stenosis 
      > 75% or > 90% in area; (e) color doppler over-estimate stenosis degree by 
      approximately 20% but was more accurate and reproducible than Vmax. An 
      appropriate procedure was designed to avoid this over estimation.
