Successful reperfusion of the Tmax>6 s region (≥60%) had 89% sensitivity and 78% specificity in predicting good clinical outcome. A reperfusion index defined by Tmax>2 s or by mean transit time>145% had much lower area under the curve in comparison to Tmax>6 s measurement (p < 0.001 and p = 0.003, respectively), and had no significant difference to recanalization at predicting clinical outcome (p = 0.58 and 0.63, respectively). In conclusion, reperfusion index calculated by Tmax>6 s is a stronger predictor of clinical outcome than recanalization or other reperfusion measures.]]> Wed 23 Feb 2022 16:03:42 AEDT ]]> Validating a predictive model of acute advanced imaging biomarkers in ischemic stroke https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:33108 Wed 06 Apr 2022 14:05:06 AEST ]]>
