• Healthy volunteers: Accepted

Summary

Using MRI, many technical parameters can be changed to optimize the diagnostic quality of the examination. The study is interventionnal because healthy volunteers are not supposed to have an MRI exam. The primary objective of this study is to optimize the imaging protocols and to validate the choice of the technical parameters in healthy volunteers. The quality of the images, cartographies or spectres will be compared to standard acquisitions. This evaluation will be based on qualitative visual criteria assessed by expert radiologists or on quantitative criteria assessed by data processing tools.

Detailed description

Using MRI, many technical parameters (sequence, parameters in the sequence, reconstruction method, etc.) can be changed to optimize the diagnostic quality of the examination. The primary objective of this study is to optimize the imaging protocols and to validate the choice of the technical parameters in healthy volunteers. The quality of the images, cartographies or spectres will be compared to standard acquisitions. This evaluation will be based on qualitative visual criteria assessed by expert radiologists or on quantitative criteria assessed by data processing tools. Prospective, single-center, observational MRI study A screening visit is planned to check the inclusion/non inclusion criteria followed by an imaging visit during which the MRI examination will be performed. Theses 2 visits are scheduled at the subject's convenience. The number of participations to the study is limited to 5 per year per subject.
