"Luxury perfusion, also sometimes referred to as post-ischaemic hyperperfusion, is a neuroradiological term used to describe regional cerebral blood flow in excess of local metabolic requirements. It is most commonly seen in the setting of reperfused cerebral infarction. Although luxury perfusion per se is not harmful, as it occurs in areas of more severe damage it implies a poorer prognosis for the affected brain 9. It is also associated with increased swelling and rate of haemorrhagic transformation 11."
"Additionally, post-ischaemic hyperperfusion has been divided into early and late forms which overlap substantially with other imaging findings. The early form, seen immediately following reperfusion is closely related, if not identical, to the angiographic blush seen during thrombolysis or endovascular clot retrieval and contrast staining seen post-procedure whereas the late form is seen hours and days later on perfusion studies 9-11."

"patients presenting with stroke-like symptoms post-seizure (e.g. Todd paresis) can have a similar pattern of hyperperfusion with increased CBV and CBF and shortened MTT 3,5"
"it should be noted that this is generally seen in status epilepticus or when scanned during seizures; in the post-ictal phase, CBV and CBF are decreased and MTT somewhat prolonged 5"

"CT and MR perfusion"
"CT perfusion usually will demonstrate elevated cerebral blood flow (CBF) and cerebral blood volume (CBV) in the affected region. Mean transit time (MTT) and time to peak (TTP) are variable but are often shortened due to arteriovenous shunting 1,6."
