A,B MRI of the brain in axial views on DWI sequence, demonstrating an area of restricted diffusion involving the right basal ganglia and coronaradiata, indicative of irreversible ischemic infarction. C,D MRP MTT maps demonstrating a large ischemic salvageable penumbra in the right MCA territory. E MRA of the brain in coronal view demonstrating a severe stenosis in the Ml segment of the right MCA (white arrow). MRI Magnetic resonance imaging; DWI Diffusion weighted imaging; MRP Magnetic resonance perfusion; MTT Mean transit time; MCA Middle cerebral artery; MRA Magnetic resonance angiography.
