The FreMRI Study: Advanced MRI on Migraine Patients Treated With Fremanezumab

MRI will be scanned prior to the first administration of Fremanezumab, within 0-14 days, prior to Fremanezumab injection. The second MRI will be acquired at 12 ± 1 weeks after the first Fremanezumab injection.Images will be acquired during interictal periods, defined as at least 24 hours from last migraine attack. All the scans will be acquired during the same session, starting with the T1-weighted scan, followed by the diffusion-weighted scan and ending with the rs-fMRI scan. Total acquisition time for a single subject is approximately 28 minutes, divided in the following periods of time: six minutes for the T1-weighted scan, 12 minutes for the diffusion-weighted scan and 10 minutes for the rs-fMRI scan. If we consider patient preparation, obtainment of documents and informed consent form, the whole process will take about 50-70 minutes.
