Je. Meyer et al., STEREOTAXIC BREAST BIOPSY OF CLUSTERED MICROCALCIFICATIONS WITH A DIRECTIONAL, VACUUM-ASSISTED DEVICE, Radiology, 204(2), 1997, pp. 575-576
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 f
ocal calcification clusters sampled with the multiple-pass technique,
12 clusters (9.2%) had no particles depicted on radiographs of the spe
cimen. Specimens from all 106 (100%) clusters sampled with the directi
onal, vacuum-assisted instrument contained calcifications at radiograp
hy. The directional, vacuum-assisted device improved the ability to pe
rcutaneously sample breast calcifications.
