Optimization of magnetic resonance imaging (MRI) protocols on healthy volunteers and voluntary patients. In MRI, a large number of technical parameters (sequence, parameters in sequence, antenna, reconstruction method, etc.) can be changed to optimize the diagnostic quality of the exam. Some optimizations can be performed on participants healthy volunteers, others need to be carried out on images pathological and acquired in voluntary patients.
An inclusion visit is planned to verify the criteria for selection, then an imaging visit to perform the MRI examination. The imaging visit can take place at the end of the inclusion visit and until the following 15 days. For healthy volunteers, the visits are organized according to their availability. For patients, on the other hand, participation in the research will depend on the programming of the MRI within the framework care. This is a single-center prospective study carried out at two sites in the Rennes University Hospital.

RECRUITINGQuality of MRI signal
The quality of the images, maps or signals collected will be compared to standard acquisitions. This evaluation will be done by statistical comparison of visual qualitative criteria by expert radiologists or on quantitative criteria drawn from analyzes computing data obtained by processing experts images (signal-to-noise ratio, contrast-to-noise ratio, blur level, mutual information, co-location of regions highlighted by different techniques, etc.).
Time frame: 15 days
