Low baseline ischemic water uptake is directly related to overestimation of CT perfusion-derived ischemic core volume

Scientific Reports, 2022
Computed-tomography perfusion (CTP) is frequently used to screen acute ischemic stroke (AIS) patients for endovascular treatment (EVT), despite known problems with ischemic “core” overestimation. This potentially leads to the unfair exclusion of patients
