My neurologist retired last summer. Before I saw his replacement, I was asked to get an MRI. Fair enough - my last one had been about 2.5 years earlier. It told me that, yes, I have MS, and that it is progressing, but pretty slowly.
When the new and the old neurologists have suggested that I get MRIs on an annual basis, my question was "why?" - I wasn't being snide, I really just want to know the logic behind me getting an MRI every year. I have fairly mild disability from my MS, I haven't switched drugs, I haven't had a relapse in several years. I guess I don't understand what (if anything) we would do differently, based on the results of an annual MRI, given my clinical presentation and the fact that my progression seems really slow.
The answer to my "why?" question usually is that "it helps us monitor things." This is when I usually ask what, in particular, would prompt a change in the status quo. Depending on the day, the answer I get ranges from, "you are right" to "do it anyway."
Let me reassure everyone that I am not against MRIs when they are warranted. Starting a new med (read: I have RRMS and just started treatment. How often should I be getting an MRI?) or experiencing new or worsening symptoms would have me much more enthusiastic about getting an MRI.
What about you? Does your neurologist have you on a schedule for MRIs? What is it? What is the rationale?
