IRM-DU is a prospective observational single center study conducted in an emergency department to evaluate the impact of a MRI scanner exclusively dedicated to emergency in the clinical management of patients presenting with dizziness or diplopia. The study will compare 2 strategies : after and before availability of a MRI scanner dedicated to emergency. The primary endpoint is the proportion of patients with a diagnosis of stroke confirmed by imaging (MRI or Computed tomography (CT)) in the group "before implementation of the emergency MRI scanner" and the group "after implementation of the emergency MRI scanner". The hypothesis is that the availability of a MRI scanner dedicated to emergency will improve the diagnosis of stroke in patients presenting with dizziness or diplopia, and will reduce Emergency Department stay, hospital stay and hospitalisation costs.
