Ultrasound Guided Core Breast Biopsies

Abstract

Core needle biopsies are common procedures performed in breast imaging centers. Utilizing ultrasound guidance for biopsy of suspicious findings within the breast and axilla is the standard of care when lesions are visible on ultrasound. Most ultrasound guided breast biopsies are performed by radiologists interpreting breast imaging who correlate findings across modalities including mammography, ultrasound and breast MRI, however interventional radiologists may perform in some practice settings. Appropriate knowledge of complete breast imaging is important not only for localization, but for determining radiologic-pathologic concordance. Proper localization, technique, and post biopsy management are essential to the success of the procedure and providing proper care for patients. This article discusses indications, strategies for accurate targeting, how-to biopsy techniques, post biopsy considerations and radiologic-pathologic concordance incorporating recommendations from the American College of Radiology Practice Parameter for the Performance of Ultrasound-guided Percutaneous Breast Interventional procedures.
