Hi.. Im new here and have a couple of questions.. I recently had a mri, with and without contrast, of my brain. The dr said there was questionable white matter. I had an mri 8 years ago bcause of ms like symptoms and that came back fine and had no further testing. I just had a evoked potential and that came back "normal". I have many symptoms of ms. my question is.. does a "normal" evoked potential automatically rule out ms? Thank you..
