The radiologist writes the MRI report, but they do not diagnose. That is up to neurologists. "Punctate focus" means "one tiny single spot". That they state "unchanged" leads me to believe it was on your previous MRI as well. They likely would know the MRI was MS protocol, so that's what the "given patient's history" part means.
At this point, although it's easier said than done, try to breath and relax until your appointment next week. Perhaps it's something, perhaps it's nothing, but it's up to the pros to sort that out. Be sure and write down any questions you have. Those appointments can kind of go by in a blur, and you don't want to leave realising you forgot to get something clarified.
No test rules MS in or out. It will be up to your neurologist to call it. I have 4 MRIs that were classic MS but I had to have a LP before my doctor would diagnose it as MS. Each doctor is different. I hope you get your answer at your appointment.
IF there is no change to the lesions from the previous mri, and they were considered by the neurologist then to be "normal", he might still consider them normal. However, he will also take into account your current situation, and evaluate the mris himself.
I had an mri that full met McDonald criteria according to the radiologist, however because the majority of the lesions were punctate, my neurologist disagreed.
At this point, I would say, only your neurologist can help you figure this out. Waiting is hard, but you don't have a long wait thankfully :).
Keep us posted!
