Very consistent with others that have similarly low levels of experience with CCSVI. We won't see consistently high levels of detection until they start believing in the equation MS=CCSVI.
I think that at GU, Buffalo, and many other places that are getting false negative results, it has more to do with the limitations of the equipment than "believing."
Ultrasound, even in the hands of the best technicians, can only see so much.
Unfortunately, only venogram can really detect and fix the stenosis. The study being done at GU, and eventually ones done elsewhere that test and treat, will show just how weak US is at diagnosing CCSVI.
But we need the studies to show US weakenss in order for every MSer to earn a venogram at diagnosis as easily as we get MRIs. It is more invasive and costly, of course. But when insurance companies see that treating CCSVI early on stops this disease from progressing, they will come on board in droves.
The cost of a venogram and angioplasty will look like pennies compared to the tens of thousands of dollars in DMDs that we cost them over our lifetimes!
And we all know that our health is really all about the $$$ to insurance and drug companies. Let them duke it out! That should be fun to watch!
