Workflow of image processing. a MRI data of multi-b value sequences and quantitative maps from ME, BE, SE and DKI models. b 3D segmentations of lesions shown as surface shaded 3D renderings. c Extraction of radiomics features, i.e., First-order, Shape, GLCM, GLSZM and GLDM. d Radiomics analysis using four models (RF, SVM, PCA-LR, and L1R-LR), and e ROC curve analysis. ROC curves are used for the comparison of four methods, and diagnostic performance of radiomics features and mean diffusion metrics
