I had a MRI last year (2 White spots that could be demyelination) and a clear LP and nothing on the evoked potential test. I had a review appointment.I still get the headaches I was referred for and the only change is my face feels stiff more frequently. I assumed it would be a waste of time and I’d be discharged. Instead he has ordered another MRI and I wondered if this is usual.
I think if you are undiagnosed, then repeat MRI’s are fairly normal, they are less frequent after a diagnosis. The MRI will show if any new lesions have appeared, which could lead to a dx if the neuro has enough clinical evidence. Hope all goes well
