NCT04906941

Brief Summary

Patients meeting the inclusion and non-inclusion criteria will be offered to participate in the study. If they agree, they will perform an MRI without injection to obtain the QSM then perform the MRI with injection that was prescribed to them as part of the care, then they will perform a second time the MRI without injection to obtain the QSM. They will also answer a short questionnaire documenting their previous exposure to gadolinium.
