Following tests after an MRI

Hi i had an MRI scan due to dizzy spells and numbness back in May to be told in July that i have Demyelinating Disease of the central nervous system so have been referred to a neuro specialist in Nov. They have said that this along with my symptons MS is highly likely. My head is all over the place at the moment and wondering if anyone else has had this in their MRI and if so did you have any other tests to confirm if you had MS. Thanks
