Évaluation de l'Impact du Compressed Sensing Sur le Signal QSM
- Conditions
- MRI
- Interventions
- Device: MRI
- Registration Number
- NCT04907487
- Lead Sponsor
- Fondation Ophtalmologique Adolphe de Rothschild
- Brief Summary
Patients who have agreed to participate in the study will complete the MRI protocol as part of routine care, to which a maximum of four additional 25-minute sequences will be added.
MRI of routine care includes at least the following sequences:
* 3D T1 TFE (2 minutes)
* T2 TSE (2 minutes)
* 3D FLAIR (3 minutes)
The sequences added by the research lasting 25 minutes are:
* SWI QSM 1.0iso 8 echoes (10 minutes)
* SWI QSM 1.0iso 8 echoes CS 6 (7 minutes)
* SWI QSM 1.0iso 8 echoes CS 9 (5 minutes)
* SWI QSM 1.0iso 8 echoes CS 12 (3 minutes)
