Summary

It is difficult to determinate prognostic criteria of Multiple Sclerosis with conventional MRI insofar as physiopathology is not well-known: the precise sequences of events leading to plaque formation and axonal injury are still not completely understood.

Some elements involved in plaque formation can be studied thanks to MR techniques (cerebrospinal fluid and periveinular spaces, neuronal injury, microglia, and cerebral microcirculation's dysfunction).

This study aims at giving a better understanding of MS plaques' physiopathology, using data from modern MRI through a longitudinal followed up with weakly MR 3T examination.

PROCEDURE

3T MR scanner

The follow-up will be scheduled for one year; it will consist in a weekly MR examination during the first two months, and subsequently on the 6th and the 12th months. We will perform for each MRI exploration an intravenous injection of contrast agents: gadobutrol (gadovist 1,0 mmol/ml) which is a stable agent with a cyclic structure. This agent is few responsible for NFS, given their low capacity to liberate gadolinium GD3+ in tissues. The same imaging protocol will be performed for each MR examination. Evaluation of creatinemia will be used before inclusion and during the 1st, 3rd, 5th, 7th, 9th, and the 10th MRI examination. Thus we will take advantage of catheter to perform the creatinemia blood test and to reduce the discomfort produced by the injection.
