The ROC curves for the GFP+ ROIs (left) and the H&E + ROIs (right) show that PpIX fluorescence has the highest specificity and sensitivity, perfect in the H&E + ROIs case, as compared to the other imaging techniques. The T1W+Gd image contrast is significantly better in the H&E + case, while the T2 map image contrast is relatively similar in both the GFP+ and H&E + ROIs. The AUC for each of the image-ROI combination is summarized in Table 1.
