Figure 6b. ROC curves for the six observers for single-view reading of the masses (a) without CAD and (b) with CAD. (a, b) R1 = reader 1, R2 = reader 2, R3 = reader 3, R4 = reader 4, R5 = reader 5, R6 = reader 6. Five of the six observers achieved an increase in the area under the ROC curve, A_z, with CAD.
