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.
