The clinical performance of digital breast tomosynthesis-guided vacuum-assisted breast biopsy: a single-institution experience in Japan

Background: Typically, prone stereotactic vacuum-assisted breast biopsy (PS-VAB) is performed when mammographic detected lesion meets the standard for biopsy, and is occult on a targeted ultrasound. Conventional stereotactic biopsy can be cumbersome and time-consuming procedure since depth information along the z-axis is determined by means of triangulation whereas this new system skip this procedure. It is expected that DBT-VAB make us easier performing stereotactic biopsy by the improvement of visibility and targeting without the process of triangulation instead provides the depth information immediately by one click. The purpose of our study is to compare the visibility of calcified lesion between 2D mammography and DBT and compare the clinical perforce of these two biopsy systems.
