Gotta second this one, I was doing good work with good correlation long before color was even available.

Please don't vilify the UM4 in a case where the technologist couldn't tell the ECA from the ICA or an occlusion from a patent artery. The UM4 has a perfectly good Doppler, one only needs to TURN IT ON. And of course, one must have the knowledge to recognize pathology and anatomy. I'd rather check my 88 year old dad's neck with a pocket Sonicaid Doppler than have an inexperienced or inadequately trained operator use the best color scanner money can buy to examine him. And since you've traveled extensively, I'm sure upon rethinking this, you realize that there are many places in the world where color Doppler is still an unobtainable dream, and yet accurate studies are being performed in the hands of excellent investigators. Leave us not descend into elitism, nor forget that many of us were performing serviceable studies before the advent of color. That's my opinion, and I'm sticking to it, (apologies to Dennis Miller.)
