Contribution of MRI to the follow-up of multiple sclerosis patients

Diagnosis criteria of multiple sclerosis (MS) have been recently reconsider ed, introducing the possibility to validate temporal dissemination with the use of MRI. In fact, MRI parameters may be considered as reflecting the bi ological activity of MS. MRI is used to monitor treatment in clinical trial s. However, and except for particular circumstances, its use in routine fol low-up of patients with MS is not recommended, because of weak correlations with clinical disability and technical difficulties of such follow-up.
