Breast sonography uses high-frequency ultrasound to characterize breast lesions, differentiate solid masses from cysts, guide biopsies, and supplement mammographic findings. It plays an especially important role in women with dense breast tissue, where mammography sensitivity is reduced.
Sonographers apply the ACR BI-RADS lexicon to describe lesion shape, margin, orientation, echogenicity, and posterior features. Common findings include simple and complex cysts, fibroadenomas, and suspicious masses requiring biopsy. Sonographers also guide procedures such as core needle biopsy, cyst aspiration, and wire localization.
The ARDMS Breast (BR) specialty examination is the dedicated credential. Many breast sonographers work in breast imaging centers, cancer centers, or hospital radiology departments alongside mammography and MRI. Breast ultrasound technologists often collaborate closely with radiologists and breast surgeons in a multidisciplinary team setting.
