Media Infarct - CT Perfusion

Noncontrast CT shows reduced differentiation between cortex and white matter as well as subtle hypodensity in the left parietal lobe. Finding of acute infarct in the posterior territory of the arteria cerebri media. Blood Flow CT Perfusion shows markedly reduced flow (blue). Blood Volume shows reduced blood volume (blue). Mean Transit Time shows increased transit time in the left parietal lobe (blue). Remember - in CT Perfusion: "Blue is Bad".
