The workflow of the radiomics signature development. a the image derived from our hospital, and patients’ informed consent was waived by the institutional review board, a region of interest (ROI) was manually delineated in the largest cross-sectional area of the lesion at CE-T1W image using a software package MaZda 4.6. b Feature extraction, a total of 279 radiomics features derived from six statistical image descriptors were extracted. c Radiomics nomogram development, features with ICC values greater than 0.75 were selected for subsequent procedure, the remaining features were reduced by using a combination feature selection algorithm of FCM, and then a radiomics nomogram was constructed using the LASSO algorithm
