Legend Restricted diffusion (ADC map not shown) in the right frontal lobe which involves white matter and cortex. Coronal and axial T2W MRI demonstrates increased signal in this region.

Legend Perfusion imaging shows decreased CBF, CBV, and increased MTT and TTP in this same region. MRA demonstrates narrowing of one M2 branch of the right MCA. Key words: mri mra perfusion vascular artery stenosis

Brain Diagnosis: Acute MCA infarct - Matched diffusion/perfusion defects
