Ultrasound-guided percutaneous breast biopsy.

Ultrasound-guided percutaneous tissue sampling of the breast has positively altered the management of breast lesions, both benign and malignant, since its inception in the 1980s and subsequent widespread acceptance in the 1990s. Its safety, accuracy, and cost-effectiveness have been validated in several studies. However, percutaneous biopsy serves a patient best when performed by an operator with full awareness of patient׳s salient imaging findings; a knowledge of the benefits, limitations, and technical requirements of breast ultrasound; and a thorough understanding of what constitutes an adequate and concordant pathologic specimen. This article outlines a general approach to ultrasound (US)-guided percutaneous breast biopsy and discusses indications, potential complications, and technical aspects of the procedure.
