The difficulty with imaging is that it's not believed by all the people who look after MS that it is useful. Many people do not believe that treating the jugular vein or the azygous vein will improve the symptom complex, and on this basis, different bodies are telling us we can't do it. For instance, in Quebec, the college said they didn't think we should be imaging for CCSVI in patients. Why, I don't know. Why the decision was made, I don't know, but I believe that decision came down roughly a week ago.
