previously been unaware of and thought it would be useful to hear other

I have worked in both dedicated vascular labs AND radiology departments. I
never seen a carotid study performed without spectral analysis in either
environment. I have seen very good and very bad practices in both.

regarding their practice. >>
OK, so here is my OPINION......
Many radiology labs DO NOT use spectral analysis for their carotid doppers.
If you haven't seen it, ...well, I HAVE. And others don't use color at all.
And even when they do, they often read it based on no specific criteria. And
I'm sure these Lifeline folks use spectral analysis and color, too.
The point is, that they are outside of the usual referral system. The
primary care physicians don't have to lose income because they have referred
someone out for a test that is probably negative and they don't have to worry
if it is positive, because they will be referred to a local lab after the
screening. For $35 the patient can rest their minds on a couple of little
You made no mention of the mobile sonographers who perform vascular exams,
many of whom are not credentialed and have absolutely no experience at
vascular sonography. What are their criteria?
Frankly, I don't see the problem here. Unless, of course, it is money.
Lifeline has been discussed in depth several months ago when they first
started their onslaught. Check the archives for that discussion.
What I would like to know is what criteria they use to call pathology and
refer back to the regular labs or primary care docs.
