Magnetic Resonance Imaging (MRI) performance depends on equipment performance, equipment maintenance and relevance of MRI sequence used. To optimize MRI performance, it's necessary to develop, optimize, test and validate new acquisition sequences for enhanced diagnosis and therapy monitoring. These new sequences will allow better spatial resolution and specificity while reducing acquisition time.

Image quality
Day 0
Signal to noise ratio
Day 0
Contrasts between structurally different regions
The values of the signal intensities will be measured in adjacent structures of interest. The difference between these values divided by the noise will be calculated to quantify the contrast-to-noise ratio between these structures. The higher this value is, the better is the sequence in its ability to differentiate these structures from one another.

Total acquisition time
Day 0
Qualitative interpretation of image quality to respiratory and cardiac motions
In the presence of improper compensation for cardiac and / or respiratory movements, the images may appear blurred. The qualitative interpretation of image quality will be performed by visual image analysis.
Day 0
MRI exam performed on 200 healthy volunteers
Procedure of the study is an MRI exam without any injection or invasive procedure, that will be performed on the Siemens Magnetom Aera imager of Liryc institute (L'Institut de RYthmologie et modélisation Cardiaque) (Xavier Arnozan site - Bordeaux)

Quantitative interpretation of image quality to respiratory and cardiac motions
In the presence of improper compensation for cardiac and / or respiratory movements, the images may appear blurred. The quantitative interpretation of image quality will be performed by a measurement of sharpness of contours between adjacent structures of interest.
