An overview of steps to predict TSS (<4.5 hrs). The SPD toolbox was used to generate perfusion parameter maps (e.g., Tmax) from the PWIs. A region of interest mask was defined on Tmax>6s region. Then, the mask was applied to the perfusion maps and MR images (DWI, ADC, and FLAIR) to generate average intensity values. A total of seven baseline average intensity features were used to train the classifiers to predict TSS<4.5hrs. Classifier performances (with and without the addition of deep features) were compared.
