Imaging Tool for Predicting Renal Clear Cell Carcinoma Fuhrman Grade: Comparing R.E.N.A.L. Nephrometry Score and CT Texture Analysis

Figure 5

The correlation coefficient heat map of texture features. The heat map shows the correlation coefficients of all 18 texture features. The red square indicates a positive correlation, and the purple square indicates a negative correlation. The correlation degree is consistent with the color depth, and the cross indicates that there is no correlation between the two features.
