The aim of this study was to evaluate the lateral arm needle guide for upright stereotactic biopsy. Conventional upright stereotactic biopsy results in the biopsy device approaching the breast often in front of the woman's face. The lateral arm enables access to the breast from the side without visualisation by the woman. Its accuracy as a needle guide has not, however, previously been documented. The results of 120 stereotactic biopsies performed using the lateral guide are presented. Our unit changed from analogue to digital at the beginning of this year and results are shown for the two machines, and by mammographic sign, in the table alongside.
