Enhancing performance of a computed tomography perfusion …

WebPatients enrolled in the SWIFT PRIME trial with baseline computed tomography perfusion (CTP) scans were included. RAPID software was used to calculate mean relative cerebral blood volume (rCBV) in hypoperfused regions, and hypoperfusion index ratio (HIR). WebPRIME protocol allowed individual centers to use either CT or MRI to select patients. The aim of the present study was to compare the clinical and imaging outcomes in SWIFT PRIME patients who were selected by diffusion/perfusion MRI versus CTP.
