Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Image quality based on standard imaging quality criteria	Image quality criteria will be : Signal to Noise Ratio and Contrast to Noise Ratio measured in arbitrary units.; absence of blurring and artefacts will be assessed by at least one radiologist according to an ordinal scale	6 months after the last inclusion
Secondary	T1/T2 Quantitative sub studies	For quantitative studies such as T1/T2 studies a T1/T2 quantification will be calculated. These parameters will be reported in ms.	6 months after the last inclusion
Secondary	Brain Functional MRI sub studies	For functional MRI studies, brain activity will be described in terms of brain localisation based on blood oxygen level-dependent signal variation and its intensity.	6 months after the last inclusion
Secondary	Cardiac function MRI sub studies: volume	For cardiac imaging, cardiac function will be evaluated. Parameters such as left ventricle (LV) and right ventricle (RV) end-diastolic volumes end-systolic volumes will be measured and reported in mL/m².	6 months after the last inclusion
Secondary	Cardiac mass MRI sub studies: mass	For cardiac imaging, cardiac function will be evaluated. LV and RV mass index will be measured and reported in g/m2.	6 months after the last inclusion
Secondary	Cardiac function MRI sub studies: ejection fraction	For cardiac imaging, cardiac function will be evaluated. Ejection fraction for both ventricles will be calculated and reported in %.	6 months after the last inclusion
Secondary	Diffusion weighted MRI sub studies	For diffusion studies, the apparent diffusion coefficient (ADC) whic is a measure of the magnitude of diffusion (of water molecules) within tissue will be estimated (mm2/s).	6 months after the last inclusion
Secondary	Diffusion tensor MRI sub studies	The fractional anisotropy (FA) which is a scalar value between zero and one, which describes the degree of anisotropy of a diffusion process, could also be estimated.	6 months after the last inclusion
