Prediction of Poststroke Hemorrhagic Transformation Using Computed Tomography Perfusion

Abstract

Tmax >14 s was the CTP parameter most strongly associated with PH. This outperformed relative cerebral blood flow <30%, which closely equates to CTP estimates of ischemic core volume. Although ischemic core volume on CTP is useful in the pretreatment prediction of PH, severe hypoperfusion on Tmax is more strongly associated and may allow better prediction of the likely anatomic location of hemorrhage.
