Abstract:
The success rate with the traditional 14-gauge, core-biopsy, multiple-pass technique was compared with that of a directional vacuum-assisted device in sampling calcification clusters in the breast. Of the 130 focal calcification clusters sampled with the multiple-pass technique, 12 clusters (9.2%) had no particles depicted on radiographs of the specimen. Specimens from all 106 (100%) clusters sampled with the directional, vacuum-assisted instrument contained calcifications at radiography. The directional, vacuum-assisted device improved the ability to percutaneously sample breast calcifications.
