Westmount Square is tempting because it's a reasonable price for just the neck ultrasound.
I went there and was reported back to my GP as 100% normal. But the guy had me doing Valsalva throughout. Another doctor (no, not a radiologist, not officially qualified but fairly smart) used a Doppler on me at 5MHz. I saw the stenoses with my own eyes. I am confident that what I saw will be visible on a venogram. I am not, and have never been, in fact I am insulted to be told that I am, normal. But especially in this case. I had heard good things about this clinic. But Zamboni, so I believe, has specified no Valsalva, and I think that made the difference. I don't know how Valsalva works but it is very temporary: not a bit like ballooning.
But if you're like me (disabled) you will want the azygous checked. That they have done Liberations before, is, I think, very important. I think there is a lot that cannot be seen without a venogram. It is often called the Gold Standard, for some reason. Dr. Sclafani says webs and such that can obstruct flow but do not appear on venogram are detectable with IVUS. I think experience, and not skepticism, are what is needed.
The Square One guy also said my venous blood had the consistency of porridge, but somehow that did not make it into his report. He expressed skepticism, saying that he had only found any of the signs in about 30% of MS people. Too many reasons not to accept the results, and if you add to that the biases of certain well-known Montreal neurologists, and the local effect of word of mouth, and, well I think I'd rather have an IR who had done Liberations, than a guy with a Doppler wand.
Of course Colin Rose would say I won't be happy until I'm told I have CCSVI, but I would rather be in the care of someone who can do something about it if I do, and I have seen my jugulars in their narrowed state. There was something in an exam mentioned here about collapsed jugulars. I think the important thing is that they are uncollapsed when you are upright, more than they would 'normally' be. So your cross-sectional area measurement comes out negative. This could happen either if the lying-down jugulars were not large enough, OR if the standing-up jugulars were not collapsed enough.
I was their last appointment for CCSVI anyway.
