MRI exam performed on 200 healthy volunteers
Device: MRI acquisitions
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)
- Image quality [ Time Frame: Day 0 ]
- Signal to noise ratio [ Time Frame: Day 0 ]
- Contrasts between structurally different regions [ Time Frame: Day 0 ]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 [ Time Frame: Day 0 ]
- Qualitative interpretation of image quality to respiratory and cardiac motions [ Time Frame: Day 0 ]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.
- Quantitative interpretation of image quality to respiratory and cardiac motions [ Time Frame: Day 0 ]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.
