Optimization of Sequences to Improve the Quality and Comfort of the Magnetic Resonance Imaging Examination

The people included will carry out an MRI comprising the sequence currently used in routine care and the different variants of the sequence being tested, for the optimization of the parameters. The duration of the examination (or the extension of the examination planned as part of patient care) will be from a few minutes to an hour depending on the sequences to be optimized. Subjects who agree to research for more than 30 minutes in the MRI machine will be compensated with a multi-brand gift voucher worth 30 euros.

Primary outcomes

  1. Quality of imagery

    Time frame: Baseline

    Quality of imagery evaluated on a likert-type scale (range from : "very bad quality" to "very good quality") by two experts

  2. Presence or absence of radiological image artifact

    Time frame: Baseline

    Presence/absence of radiological image artifact evaluated on a likert-type scale (range from : "major - impossible interpretation" to "none") by two experts

  3. Confidence in diagnosis

    Time frame: Baseline

    Confidence in diagnosis evaluated on a likert-type scale (range from : "not confident" to "very confident") by two experts
