The data support the feasibility of US for discriminating malignant from benign findings corresponding to the ACR BI-RADS classification without excessively increasing the number of unnecessary biopsies.

Breast ultrasound should be the preferred imaging procedure in the case of a palpable lump, leading to a definitive diagnosis itself or with an additional consecutive core needle biopsy. For women without symptoms, breast sonography should be mandatory and complementary to mammography in the case of breast density grade II (BI-RADS) or more. Application of breast ultrasound as a primary method or an alternative to mammography has not yet been evaluated sufficiently. It seems advisable in the case of women with dense breast tissue grade III and IV, women under the age of 50 and high-risk women. The implementation of breast ultrasound in this manner has to be checked by future trials.
