Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Image quality based on standard imaging quality criteria [ Time Frame: 6 months after the last inclusion ]

    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


Secondary Outcome Measures :
  1. T1/T2 Quantitative sub studies [ Time Frame: 6 months after the last inclusion ]
    For quantitative studies such as T1/T2 studies a T1/T2 quantification will be calculated. These parameters will be reported in ms.

  2. Brain Functional MRI sub studies [ Time Frame: 6 months after the last inclusion ]
    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.

  3. Cardiac function MRI sub studies: volume [ Time Frame: 6 months after the last inclusion ]
    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.

  4. Cardiac mass MRI sub studies: mass [ Time Frame: 6 months after the last inclusion ]
    For cardiac imaging, cardiac function will be evaluated. LV and RV mass index will be measured and reported in g/m2.

  5. Cardiac function MRI sub studies: ejection fraction [ Time Frame: 6 months after the last inclusion ]
    For cardiac imaging, cardiac function will be evaluated. Ejection fraction for both ventricles will be calculated and reported in %.

  6. Diffusion weighted MRI sub studies [ Time Frame: 6 months after the last inclusion ]
    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).

  7. Diffusion tensor MRI sub studies [ Time Frame: 6 months after the last inclusion ]
    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.
