An MRI-compatible semiautomated vacuum-assisted breast biopsy system: initial feasibility study.

Purpose: To develop an MR-compatible vacuum-assisted core needle breast biopsy system.

Materials And Methods: A vacuum-assisted breast biopsy system (Mammotome Hand Held; Ethicon Endo-Surgery, USA) was modified for freehand MRI-guided biopsy in an open, interventional 0.5-T scanner (Signa SP; GE, USA).
