Diagnostic performance based on b800 and b1500 DW images was not uniform
among 3 readers. Beside b values attention should be given to standardization
on reading protocols and experience from DWI readers.
Figure 3. The DW image findings are different among 3 readers. Fibroadenoma.
Table 1. Agreement
in DW-based BI-RADS categories. Agreement in DW-based BI-RADS categories tended to be higher in b1500 compared to b800 DW images. Mean and confidence intervals for kappa values are shown.
