The PERFusion Use in Stroke Evaluation Study "PERFUSE"


Phase N/A Results N/A

Trial Description

This is an open label single center phase II trial, evaluating the utility of 64 slice CT perfusion (CTP) in acute ischemic stroke (AIS) patients. The main aim is to determine which aspects of CTP imaging can aid in expanding the time window for thrombolysis with IV (rt-PA) in AIS patients up to 6 hours after symptom onset.
