Scatter plots joining the three features: (i) surface–volume ratio, (ii) surface area, and (iii) long-run high-gray-level emphasis of local kurtosis extracted from all patients (i.e., lbp-3D-k, glrlm, LongRunHighGrayLevelEmphasis in PyRadiomics), including both the 3 T training and 1.5 T testing cohorts, which were consistently selected by the proposed BB-RENT method and which were assigned negative coefficients with highest magnitudes across all five folds in the model-training phase. These three features extracted from the T2-weighted, fat-suppressed MRI exhibited potential to discriminate early NPC from benign hyperplasia and were selected by BB-RENT from a total of 422 features. NPC = nasopharyngeal carcinoma, LRHGE = long-run high-gray-level emphasis.
