What is it indicated for?

The Mammotome Prima™ MR Vacuum-Assisted Breast Biopsy System is intended to acquire breast tissue from an imaged abnormality during MRI-guided breast biopsy procedures for histologic examination.

The extent of a histologic abnormality cannot always be reliably determined from an imaged appearance. Therefore, the extent of removal of the imaged evidence of an abnormality does not predict the extent of removal of a histologic abnormality, e.g., malignancy. When the sampled abnormality is not histologically benign, it is essential that the tissue margins be examined for completeness of removal using standard surgical procedures.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
