Fig. 5From: Better efficacy in differentiating WHO grade II from III oligodendrogliomas with machine-learning than radiologist’s reading from conventional T1 contrast-enhanced and fluid attenuated inversion recovery imagesThe calculated principal components for each tumor type were demonstrated based on the tumor tissue heterogeneity. II = ODG2, III = ODG3; component 1 = first principal component, component 2 = second principal component, component 3 = third principal component; a = T1 CE; b = FLAIR; c = T1 CE + FLAIRBack to article page
