Intraoperative ultrasound and other techniques to achieve negative margins.

Over the past few decades new procedures and technologies have been introduced into clinical practice for the evaluation and management of breast disease. Ultrasound is rapidly becoming a valued tool in the armamentarium of the breast surgeon. The use of ultrasound by radiologists and breast surgeons to evaluate nonpalpalable detected breast lesions has increased dramatically. With its easy portability and improvements in the technology, the use of ultrasound has now expanded into the operating room. In this work we review the value of intraoperative ultrasound and other techniques in obtaining and assessing margin status.
