Just wanted to put out there that Arizona Doppler Specialist does excellent Doppler Sonograms using the Zamboni Protocol, to DX CCSVI, and it is less expensive than the Haake Protocol. Certainly not as thorough, but if you want a basic DX, this is an option.
I had my CCSVI DX by Eric Feigenbutz. To DX CCSVI takes special ultrasound training… you can’t just get it done at your local hospital, sadly.
Also, Arizona Doppler does go to other locations to do US’s… that is how I had mine done, in Seattle in Jan 2011 during an MS mini conference of sorts. So you can always check with them to see if they are going to be in any other locations.
