3T MRI7T MRIClinical examination of MS patientsNeuropsychological testing of MS patientsQuality of life questionnaires

3T MRI: For this intervention, subjects will undergo a 3T MRI. The duration of an MRI session will not exceed 1h30

7T MRI: For this intervention, healthy subjects and patients will undergo a 7T MRI. The duration of an MRI session will not exceed 1h30

Clinical examination of MS patients: During this interevention, patients will be submitted to 2 tests the EDSS and the MSFC scores, assessing for physical and cognitive disabilities in patients.

Neuropsychological testing of MS patients: This interventions consists in submitting MS patients to diverses neurpsychological tests assessing various parameters: CSCT (Computerized Speed Cognitive Test) for speed of information processing. PASAT (Paced Auditory Serial Addition Test) fo executive functions, working memory and attention CVLT (California Verbal Learning Test) for verbal episodic memory BVMTR (Brief Visual Memory Test) for visual episodic memory Fluences for mental flexibility, attention, lexical access "Test des commissions" for Ecological evaluation of executive functions Moreover, patients will fill out auto-questionnaires of quality of life including: a self-questionnaire of laterality (EDINBURGH), fatigue (MFIS), depression (BECK), anxiety (STAI1 and STAI2), quality of life (MUSIQOL), sleep quality (PITTSBURGH) and cognitive complaint (PDQ) will be collected for the volunteers.

Quality of life questionnaires: This intervention consists in the completion diverse questionnaire assessing the quelity of life of the subject. These questionnaires include: a self-questionnaire of laterality (EDINBURGH), fatigue (MFIS), depression (BECK), anxiety (STAI1 and STAI2), quality of life (MUSIQOL), sleep quality (PITTSBURGH) and cognitive complaint (PDQ) will be collected for the volunteers. The completion of the self-questionnaires will take about 30 minutes.

Study summary

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.

Primary outcome measure(s)

Assessing the feasibility of an accelerated 3T and 7T qMRI approach — Day 1
Sensitivity per unit of acquisition time (signal-to-noise ratio, SNR), short-term inter-examination reproducibility (intra-individual repeatability), as well as the minimum acquisition duration
To estimate standard values of qMRI biomarkers — Day 1
qMRI metrics calculated over region of interests defined in white and gray matter, mean and standard deviation of qMRI parameters
To estimate normative inter-examination reproducibility of qMRI biomarkers — During the first visit at Day 1 and during the second visit at day 60
Inter-examination reproducibility (intra-individual repeatability)
