When patients arrive in the waiting room of the MRI department, patients will be given the briefing note explaining the purpose of the study and how it is going. During the consultation, the radiologist will check the inclusion and non-inclusion criteria, and will take the time to answer all of the patient's questions about the study (or his family member by telephone if the patient does not is not in a condition to give its consent).
The MRI examination will be performed on a 3T multi-parametric MRI. If the neurological disorder presented by the patient does not require an injection as part of routine care, only a high resolution 3D T2 sequence on the nasosinus cavities and the olfactory tract, called bFFE-Xd for approximately 2 min.
If the neurological disorder presented by the patient requires an injection as part of current care, the examination will be completed with the nasosinus and olfactory 3D bFFE-Xd sequence, and the following additional sequences performed after post injection: a
