Brief Summary
Through this phase IV study, multicenter prospective exploratory, uncontrolled, the investigators propose to identify MRI predictive factors of treatment response, using diffusion MRI sequences, in addition to conventional sequences. The primary objective is to study the links between changes on MRI diffusion and response to treatment with Tysabri to 2 years. The secondary objective is to compare the evolution of diffusion MRI data with the volumetric MRI data.

Outcome Measures
Primary Outcomes (1)
Comparaison of diffusion Magnetic Resonance Imaging before and after the initiation of treatment with Tysabri using fractional anisotropy (FA).
24 months
Secondary Outcomes (1)
Comparison of different Magnetic Resonance Imaging criteria before and after treatment
24 months
Study Arms (1)
Magnetic Resonance Imaging at 6 months
EXPERIMENTAL2-year follow-up MRI of patients initiating treatment with Tysabri with anti-JCV antibody positive or negative. Patients enrolled will benefit from diffusion MRI at 6 months, in addition to conventional MRI.
Interventions
2-year follow-up MRI of patients initiating treatment with Tysabri with anti-JCV antibody positive or negative. Patients enrolled will benefit from diffusion MRI at 6 months, in addition to conventional MRI.
