I asked about that, because it was a new machine. However, it was the same tesla, a closed machine (as was the old one), and the "old" one was already seen as one of the best machines in Houston. When I asked about it, she said that the "new" lesions were quite distinct and in new locations, and the old scan showed no hint of anything there before. Her opinion based on the change in resolution around the previously existing lesions was that the new ones truly were new and it was not just a change in resolution from the machine that made them visible.

She actually took me into her office and we looked at the scans on her computer monitor and after having it pointed out to me what she was looking at, I tend to agree with her.

As for her opinion on the cognitive issues, she said they could be causing it, but she advised against doing any further cognitive function testing (I had a baseline before I knew I had MS for other reasons) until I have a reason to need to know. She said such testing can be used against you by insurance companies, employers, etc. and it is better not to do it until you need it to prove something yourself (such as SSDI claims).
