Fig 2. A 53-year-old man with complaint of acute left hemiparesis, presented within 3 hours of symptom onset.
A, Initial NCCT showed subtle hypoattenuation in the right frontal lobe with loss of gray-white distinction suspicious for AIS.
B, C, and D, CBF, CBV, and TTP color maps, respectively, showed hypoperfusion in the right basal ganglia and frontal lobe consistent with right MCA AIS.
E, PS color map, from the same raw data used to create the perfusion maps, showed PSinfarct of 8.1 mL/100 mL per minute. Emergent intravenous rtPA was given.
F, NCCT 27 hours after initial presentation revealed frank hemorrhage in the region of infarction (PH1). The patient developed acute deterioration of his mental status 1 hour before this CT.
