Patricia, I was under the same impression...that lesions in the spinal canal would show up in MRI's. But, my docs are giving me a lumbar puncture, since the "brain" MRI showed leisions. I am also getting a new MRI of my spine...but, I don't think it is to find lesions. I think it is to see what progression there may be.

Good question: Can lesions in the spinal canal be picked up in an MRI?????
