Acute infarction with no ischemic penumbra: 75 years old female patient complaining of left hemiplegia since 10 h. A T2WI, B FLAIR, C SWI, D DWI, and E ADC map show acute ischemic infarct at the right frontoparietal region along the territory of the right MCA. ASPECTS score was 3/10. F ASL perfusion at 1.5 s shows corresponding area of hypo perfusion (no diffusion perfusion mismatch) without ischemic penumbra, aCBF = 11 mL/gm 100/min—rCBF = 62% to contra lateral side. aCBF absolute cerebral blood flow, ADC apparent diffusion coefficient, ASL arterial spin labeling, ASPECT Alberta Stroke Program Early CT Score, DWI diffusion weighted image, rCBF relative cerebral blood flow, SWI susceptibility weighted image
