RECRUITINGImage quality based on standard imaging quality criteria.
The image quality will be appreciated visually at least by a radiologist or a researcher.
Time frame: 6 months after the last inclusion
Comparison of the Signal to Noise Ratio obtained by the optimized MRI sequence and the reference situation (standard sequence).
Signal to Noise Ratio will be measured in arbitrary units.
Time frame: 6 months after the last inclusion
Comparison of the Contrast to Noise Ratio obtained by the optimized MRI sequence and the reference situation (standard sequence).
Contrast to Noise Ratio will be measured in arbitrary units.
Time frame: 6 months after the last inclusion
Comparison of the acquisition time obtained with the optimized MRI sequence and the reference situation (standard sequence).
Time acquisition will be evaluated in minutes.
Time frame: 6 months after the last inclusion
Comparison of blurring and artefacts obtained by the optimized MRI sequence and the reference situation (standard sequence).
Absence of blurring and artefacts will be assessed by at least one radiologist according to an ordinal scale.
Time frame: 6 months after the last inclusion
Comparison of the spatial resolution obtained by the optimized MRI sequence and the reference situation (standard sequence).
Spatial resolution will be measured in mm².
Time frame: 6 months after the last inclusion

Validation of MRI acquisition by a centralized review center.
Time frame: 6 months after the inclusion
Evaluation of intra-subject reproducibility on the same MRI and on two MRIs.
Measurement of intra-subject reproducibility on the same MRI and on two MRIs by the intra-class correlation coefficient for quantitative measurement or by the kappa coefficient for a qualitative measurement.
