RAPID has detected some TMAX deficits which when you look at the slightly lower threshold of 4s (blue region in the summary panel) looks very nonvascular and likely artefactual. Looking at the TMAX images, however, you will see that the striking abnormality is how low TMAX is in the right hemisphere (with some sparing of the primary motor and somatosensory cortices). Identifying that the abnormal side is the right side, you can tell that the assymetries in the CBF and CBV imply that there is increased perfusion to the right hemisphere (and not decreased perfusion to the left).

CTA images show no vascular occlusion but early venous opacification throughout the right hemisphere, matching the conclusion from perfusion that there is elevated perfusion and blood flow to the right. This person was in status epilepticus (subclinical) at the time of the CTA/CTP with seizure onset in the right hemisphere based on EEG obtained 30 minutes later. Remember seizures (and migraines) when you have odd perfusion patterns such as this case.
