Vick, did you have that CCSVI done by Dr. McDonald? If yes, then he seems very pro-MSer and should be able to help you. If it wasn't done by him, then perhaps contact his office to arrange a meeting. Was the test you had done just a Dopplar ultrasound, or a venogram (apparently the "gold standard" to testing for CCSVI)? In Poland I had the Doppler, MRV beforehand and then a venogram during the procedure.
If you really need to get a MRV, maybe try to get in contact with Dr. Haacke at McMaster University. There are also some contacts on the TiMS and facebook CCSVI sites, I believe. But I think getting in contact with Dr. McDonald might be the best idea, either directly or through a referral from your GP.
