If their sonographer was trained in the Zamboni protocol they will find CCSVI - if it exists. Consistency and standardization in the protocol is what is needed for patients to get an accurate diagnosis. By changing or adding to the protocol based on their opinion only skews validity and ultimately affects patients getting treatment.
Or maybe they've just got good sonographers who don't press down too hard and therefore don't end up seeing things that aren't there?
