    Abstract:
    Since few years a new vacuum-assisted biopsy is used in addition to the common gun-needle biopsy in suspicious lesions of the mamma. Aim of our study was to compare these two techniques in regard to their histological outcome. Retrospectively, 149 of the 1997 performed biopsies and the corresponding operation specimens were evaluated. The biopsied lesions were divided in star-like densities, roundish opacities and different forms of microcalcifications. We found both stereotactical methods very accurate. In vacuum-assisted biopsies more representative material could be obtained in cases of microcalcifications. The better quality of the tissues made the histological result more reliable. In concern to other lesions in the mammogram there was no difference between the two techniques at all. In summary, both stereotactical methods revealed comparable and valuable results whereas in any form of microcalcifications we suggest to apply the vacuum-assisted method.
