Breast ultrasound is an important diagnostic tool, mainly used in the differentiation between cystic and solid lesions of the breast. It is applied complementarily to mammography in women with mammographically dense breasts, as well as for further investigation and characterization of any suspicious finding. An ultrasound BI-RADS classification system, similar to the mammography one, has been developed, in order to optimize the lesion’s characterization. Combination of breast ultrasound with elastography seems to increase the specificity and the positive predictive value, compared to conventional ultrasound alone. However, its applications are not limited to the lesion’s assessment. It is equally used in the evaluation of axillary lymph nodes, as well as to guide interventional procedures both in breast and axillary region. It can also be helpful to localize, evaluate, and biopsy lesions revealed by breast MRI. Currently, with the introduction of new high-resolution probes, investigators evaluate a possible role of breast ultrasound for screening purposes.
