This study aims to develop the use of a quantitative MRI (qMRI) approach in neuroimaging for MS patients.
To achieve this task the main goals of this study will be:
* to standardize and optimize qMRI protocols (acquisition time, sensitivity)
* to acquire ranges of normative values of qMRI parameters as a function of age and sex at high fields (3 Tesla) and ultra-high fields (UHF for ultra-high field, 7 Tesla)
* To develop integrated tools for image processing and the generation of normative models of the healthy brain normative values
* To assess the clinical feasibility and the multicenter validation of the multiparametric tools proposed in the case of application to MS.
