Hey Mac's Mum,
What they are look for is current inflammation. It seems from your report that you have two lesions on your cervical spine area but that neither one is actively flaring. The dye is meant to cross the blood/brain barrier and will find active demyelination.
I no longer do the dye now that I am diagnosed. It is sorta not so good for you.

I have no lesions on my soul and so I will live with no limits.
