Thin breasts and shallow lesions are commonly encountered problems that preclude safe stereotactic core biopsy with a vertical approach using erect add-on stereotactic biopsy systems. A simple method to measure breast thickness and depth of lesion using conventional erect add-on stereotactic biopsy systems is outlined. A spinal needle and its needle guides are the only additional instruments required. The measurements obtained indicate the feasibility of stereotactic core biopsy, thus avoiding unnecessary puncture and facilitating planning of alternative biopsy methods.
