"Because MRI is particularly useful in detecting central nervous system demyelination, it is a powerful tool in helping to establish the diagnosis of MS. It should be remembered, however, that approximately 5% of patients with clinically definite MS do not show lesions on MRI, and the absence of demyelination on MRI does not rule out MS. Also, since many lesions seen on MRI may be in so-called "silent" areas of the brain, it is not always possible to make a specific correlation between what is seen on the MRI scan and the patient's clinical signs and symptoms."
