Patients who present with symptoms of stroke and who demonstrate hypodensity on ct within first six hours were proven to have larger infarct volumes more severe symptoms less favorable clinical courses and they even have a higher risk of hemorrhage. It allows both the core of the infarct that part destined to never recover regardless of reperfusion to be identified as well as the surrounding.

Ct perfusion has emerged as a critical tool in selecting patients for reperfusion therapy as well as increasing the accurate diagnosis of ischemic stroke among non expert readers four fold compared to routine non contrast ct 9.
