3.2 Comparison of Radiomics Features Between CCSK and Wilms’ tumor
Based on the final features from CMP, NP and CMP+NP, ROC curves of each feature were demonstrated in Fig. 2 , and the values of AUC, sensitivity and specificity were listed in Table 1 . The results showed first-order features from NP images have a better diagnostic performance than those from CMP images. Generally, a value of AUC between 0.8 and 0.9 indicates good diagnostic efficacy, and between 0.7 and 0.8 moderate diagnostic efficacy. Skewness from NP images filtered by exponential and squareroot filters were the most meaningful features to differentiate CCSK from Wilms’ tumor.
