Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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)
