Table 5.

Average area under ROC, Az, for the Independent mode, Sequential mode without CAD, and Sequential mode with CAD. The scales in terms of LM and BI-RADS are the original readings, LM-6 Categories is the linear binning from the 101-rating scale to 6 rating scale shown in Table 2, the mappings LM→BI-RADS(r5) and LM→BI- RADS(7) are described in Table 1. The average Az values for the mapping LM→BI- RADS(5) are not shown because the MRMC program failed to converge for two of the radiologist readings (Tables 6).
