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.
