Fig 1.

55-year-old man with right homonymous hemianopsia and right-body hemisensory loss. Admission nonenhanced CT 6 hours after symptom onset was unremarkable (both reviewers), except for an attenuated left PCA (arrowheads, one reviewer). PCT shows prolonged MTT and reduced rCBF in the left PCA territory. rCBVs are reduced only in a small part of the left thalamus but are increased in the rest of the PCA territory. The areas correspond to infarct and penumbra on the computerized automated map. Figure and legend continues.
