Figure 1.

A non-intervention case for a middle cerebral artery occlusion patient. Top and middle rows show Bayesian and SVD+ perfusion analyses, respectively. Red, yellow, and purple regions indicate infarct, penumbra, and ventricles, respectively. The bottom row indicates FLAIR MRI 24 hours post CTP imaging, with hyper-intensified regions indicating infarct. SVD+: singular value decomposition plus; FLAIR: fluid-attenuation inversion recovery; MRI: magnetic resonance imaging; CTP: computed tomography perfusion.
