Digital breast Tomosynthesis vacuum assisted biopsy for Tomosynthesis-detected Sonographically occult lesions.

PURPOSE To assess the utility and pathological results from DBT VAB for lesions occult on 2D mammography and breast ultrasound (US). MATERIALS AND METHODS A retrospective review of 1116 consecutive stereotactic biopsies was performed over 27months. DBT VAB was performed for 38 non-calcified lesions which were solely detected using DBT. Imaging findings and pathology results were reviewed. RESULTS Pathologic findings were malignant in 8 of 38 lesions [masses (5) and distortion (3)]. High-risk findings found in 14 lesions. CONCLUSION DBT VAB is easily performed and the majority of cases yield actionable pathologies. Therefore, perform DBT VAB primarily when available.
