Thanks Johanna. I tried doing a search to see if I could find Dr Jordan's protocol. I'd like to ask this dr how his protocol is similar or different. I think he is a vascular surgeon and their follow up test is some sort of ct-angiogram. Since mine is mostly neuro, I doubt that will be my route.
btw-here is an interesting info on the MRA done by Dr Werden, the dr who does the MRA in No CA
