Optimized MRI Sequences
Conditions
Brief summary
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.
