[|AI|]  Hi I am Chat Doctor.  As a radiology expert let me tell you that ms can have typical as well as atypical symptoms. Ct scan is not the imaging modality of choice. It is MRI of brain and that too with intravenous contrast to check for active disease. So first you didn't mention why your name being work DUP for ms. if so there are also many blood tests and CSF tests available. So just don't relax on the symptoms if they are atypical of ms. get a MRI done, thanks.
