Just one caution, having "contrast" with tests may not always be a good idea. Some people react badly to it. MRI can show a lot without contrast fluids. I have had many without contrast.
When I hear stories of people living long with MS, I include myself among them. My aunt died at 50, though. I think she would have benefitted from the Swank MS diet, as I have. I mention it because you're a "newbie" and may not have heard of it. People have various reactions to it, but we all know about it...but maybe a newbie does not know about it. I know that it helped me...and it could have helped my aunt, who ate a very high fat diet, favored by her Scottish mother (the Scots are eaters of biscuits, high fat meats, high fat deserts, etc.). The Swank diet was recommended to me by a doctor who had MS. Books available in most libraries.
