ROC curves.

<p>The ROC curves are plotted for the experienced (top row) and trainee (bottom row) for all 288 breasts (left column) that were normal (n = 181) or tumor bearing (107) and the breasts with small tumors (<5mm³) (n = 58) and the associated normal breasts within the same animals (right column). Note that the AUC improved for both observers after ACPPD-Gd but the improvement was more significant for the trainee.
