Integration of DCE-MRI and DW-MRI Quantitative Parameters for Breast Lesion Classification

Figure 2

Receiver operating curves (ROCs) of single features in the case of voxel-by-voxel analysis. Per each feature (see Table 2) the ROC is reported in terms of true positive rate (TPR) and false positive rate (FPR). The plots have been aligned according to the area under curve (AUC) in row-wise descending order with the largest AUC at the top-left. The red dot indicates the best compromise between TRP/FPR considering the unbalance between benign-malignant subjects. FPR is generally very high except for and HR.
