Differential bore sheath breast biopsy--a pilot study of a new technique

The increasing requirement for core biopsy in the diagnosis of early breast disease puts additional demands on radiologists' time and expertise. We present a new approach to percutaneous breast biopsy of impalpable lesions with core biopsy and simultaneous hook wire localization. The technique allows accurate localization of breast lesions and is unique in that it facilitates simultaneous hook wire localization. Percutaneous biopsy by this method was accurate in 9 of 11 patients.
