Fig. 7From: Convolutional neural network-based magnetic resonance image differentiation of filum terminale ependymomas from schwannomasRegions of interest of the diagnostic system computed by Grad-CAM. A, B and C are ependymomas, corresponding to T1-WI, T2-WI, and CE-T1, respectively. D, E and F are schwannomas, corresponding to T1-WI, T2-WI, and CE-T1, respectively. The areas that appear more red indicate that the model pays more attention to those regionsBack to article page
