Time will tell, Nick.
With MS, they are looking for the right size, shape and location of the "dots" (lesions), combined with a clinical history suggestive of MS. They want to see changes over time, both physically and in the MRI results, if the initial results are inconclusive.
Attached is a list of 100 differential dx, and information on how they dx MS. There is no blood test (or any other kind of test) that CONFIRMS MS, it's a matter of them ruling out all other potential causes, then putting the pieces together, usually over TIME.

If you have any further changes in symptoms in the future, it is probably worthwhile to have further brain and C & T spine MRIs.
