Hi kadedoll, and welcome! I completely agree with Mark and Froggie's posts, but I wanted to say hello and add a couple of comments. Gadolinium is given just like Mark said - at the end of the main set of MRIs - but its pupose is to enhance any lesions that are "active" at the time. My very first brain MRIs were done with no gad at all, and still showed my brain was full of 'classic' MS lesions = instant dx. My next 2 sets of MRIs (1 yr & 2 yrs later) showed no noticeable change in lesions and NONE of them enhanced. Eight yrs later - those lesions are still there and they still don't light up.
And for those who don't already know this, EMGs are to test for peripheral nerve damage, and are not a specific test to dx MS. All neurological problems cause similar symptoms, so the trick is to narrow down the cause of yours. Since I have both central and peripheral nerve issues, my neuro admits that it's impossible to pin many of my symptoms on either the CNS or PNS alone.
But Froggie makes a good point:
If you can, you may want to get a second opinion. Seeing a neurologist is a good idea in that if it's not MS, they may have a better idea of what's going on.
And the eye doctor appointment is also a great idea.
Welcome again, make yourself at home, and keep us posted how things go for you!
