This prospective observational study will evaluate the potential value of mobile MRI in patients with suspected or proven acute stroke and Transient Ischemic Attack (TIA), undertaking additional imaging in the emergency department, acute stroke unit, or outpatient settings, and comparing diagnostic accuracy, Diffusion-weighted imaging (DWI) lesion volume and detection of complications (brain swelling or haemorrhagic transformation). Information on ease of use, tolerability and image quality will also be gathered.
The study will investigate mobile MRI for immediate radiological acute cerebral lesion evaluation in Stroke. The objectives are:
