Hey Bonnie, you did mention that you first scanned from the head of the
bed? And did you change for convenience ( note, I didn't say laziness) or
for improved accuracy? And I'm pretty sure when I first met you were
doing it from the head, too bad you went over to the "dark side".

OUCH!!! from the "B" team?!!!! (does 98% accuracy count for anything?)

Don, scanning from the side of the patient is being taught in some
ultrasound schools, and I think it's a mistake. The key ingredients to a
successful technical carotid scan include the ability to hold a 1 or 2 mm
Doppler sample volume in a 1mm or 1/2 mm residual lumen and keep it
there.  Anyone can do normal carotids, but it's the tough ones that
require a very steady hand/arm and very subtle transducer movement. One's
arm cannot be resting on the patients chest. Additionally, the ability to
scan from a posterior -lateral position is essential. These two critical
ingredients are difficult  when positioned at the patients side. I've met
a lot of people who scan carotids and all of the people that I consider
to be the "A team" scan from in front of the head, and it's for a good
reason.  If you want to achieve the best quality exam, you can't cut
 corners on technique. My apologies for preaching to the choir, but I'm
concerned about what I consider to be an erosion of carotid scanning

This isn't what you'd call Earth-shaking, but there's a bit of a bet:

What position are people taking relative to the patient when scanning
carotids? I'm still of the old school, sitting behind the patient's head.
Another tech tells me nobody scans like that any more; he stands at the
patient's side, facing the patient, much as one would doing an abdominal
scan but a bit farther toward the head.

Could I ask for a bit of a survey? There's a lunch riding on this. You
reply straight to me so as not to clutter the Flownet up severely:
