Thank you both, Gretchen and Uppity... the tech was very clear that the other MRI's were fine but this radiologist told my neuro he also wanted the lumbar region and then overlap into the thoracic as well... I asked if I had moved or goofed up the other one... and she said no it was fine but this dr is thorough and wants an overlap and more... so I suspect he's found something that will confirm the symptoms... and yes, Uppity, I'm mighty glad it's not invasive! :) I'm just not good with the coffin like cylinder thing and noise. The tech does a good job though providing ear plugs, muffs and a cloth for my eyes... it does help.
The problem has been no lesions in the brain, but the neuro never checked the spine before and most all my major symptoms are below the waist in mobility, GI tract, but then the extremities of arms/hands/ and partial face numb spots and the optic neuritis, along with dizzyness/ imbalance, the eye tics, and spasticity etc all seemed to add up to just this MS. So it may well be that I don't have many lesions but the ones I do are in critical areas. Heck one of his own big books (I had too much waiting time in his office one day) says 1% of the MS patients don't show lesions at all... so it's hard to confirm it then but it still happens.
I am enjoying this forum greatly... there's a lot of stuff a lot of people around well-meaningly want to share with me or tell me about but I've explained to them that I've got alot of resources and need to listen to experience (here) and my doctors first... then I'll listen to all the other stuff. Thanks always for being here... this has been a good refuge already.
