Fig. 1From: The value of radiomics based on dual-energy CT for differentiating benign from malignant solitary pulmonary nodulesFlow chart of the radiomics analysis steps. Two radiologists manually segmented the region of interest (ROI) of pulmonary nodules. For model construction, the radiomic features were extracted, and principal component analysis was performed. The area under the curve (AUC) of the review operating characteristic was used to assess the diagnostic accuracy of the models. Decision curve analysis was used to assess the clinical utility of the modelsBack to article page
