Many factors contribute to MR-guided breast biopsy procedure success or failure. Significantly, there is no immediate verification of specimen retrieval and no quantitative measures to indicate adequate removal of the enhancing lesion. This work demonstrates a tool enabling quantitative assessment of success of MR-guided breast biopsy. Results from 4 patients indicated that the ratio between volumes of the suspicious lesion and total tissue removed in a biopsy procedure averaged 52%, ranging from 4% to 99%. The availability of real time quantitative assessment of lesion removal, prior to procedure completion, should enable improved verification of lesion sampling.
