My neuro said the only way to know 100% where our lesions are is during an autopsy.
I don't know about you, but I am not ready for an autopsy yet.
We know from symptoms that I have a lesion on my spine but it hasn't shown up on MRI. I guess I should clarify that by saying that of the ones I have seen. Since I've been in this clinical trial, none of my MRIs since Jan of 2007 are available for review by the trial doc nor my neuro.
