Fig. 1

Overall schematic framework of the radiomics analysis: (a) MR images across preprocessing of bias field correction and intensity normalization; (b) Margin variations consisting of erosion, smoothing, and dilation of various sizes on each slice of volume of interest (VOI), which represent diverse VOI delineations; (c) Radiomics features extracted from varying parameter settings and feature selection; (d) Radiomics analysis mainly consisting of feature robustness analysis, feature selection analysis, and predictive performance comparison of models from diverse VOIs
