To those of you with experience doing TCD exams: Is it incorrect or unreliable to use continuous wave doppler on high velocities? I use continuous wave when I get really high velocities and can not adjust my scale any further to eliminate aliasing. Does this render my findings incorrect? Any feedback will be appreciated.
