BI-RADS is routinely used in clinical practice for reporting mammographic breast density [].In previous studies, however, researchers found that the assignment of density categories showed varying degrees of agreement among radiologists ( = 0.43-0.76) [2-4].Thus, there is increasing interest in the use of quantitative measures derived from mammographic images. The use of density determination is now mandatory in some states in the United States, and patients must be informed of the fact that they have "dense" breasts, which usually is defined as heterogeneously dense or extremely dense.
