At needle localization of breast lesions, marker placement under sonographic guidance is beneficial because it enables immediate confirmation of accurate surgical removal of the localized lesion at surgical excision. Use of marker placement, however, does not reduce the percentage of cases with close margins necessitating reexcision

Complete excision of the MRI target occurred in 30% of breast cancers diagnosed at MRI-guided vacuum-assisted biopsy. Among cancers in which the MRI target was percutaneously excised, surgery yielded residual cancer in 64%. Complete removal of the MRI target does not ensure complete histologic excision of the cancer.
