Breast imaging
Published in David A Lisle, Imaging for Students, 2012
Core biopsy may be performed under US or mammographic guidance with 14–18 gauge cutting needles that obtain a core of tissue for histological diagnosis. A variation of core biopsy is vacuum-assisted core biopsy (Mammotome®). A Mammotome consists of an 11 gauge probe that is positioned under mammographic control. A vacuum pulls a small sample of breast tissue into the probe; this is cut off and transported back through the probe into a specimen chamber. This technique is particularly useful for microcalcification.

Biopsy markers have proven to be generally safe with very few incidences of adverse events (AE) documented in the literature. Reports of AEs have been mostly centered on marker migration/displacement, disappearance, and allergic reactions [4,6–11]. Most of the studies done to evaluate adverse effects involved smaller sample sizes and case reports [11,12]. To our knowledge, no study in the literature has gone beyond device-related adverse effects to investigate device deficiencies (DD) or malfunction. This study focused on the MammoMARK, CorMARK, and HydroMARK biopsy site markers (Mammotome, Devicor Medical Products, Inc., part of Leica Biosystems, USA (Global Headquarters). The purpose of this study is to characterize the safety and performance of these three specific breast biopsy site markers by evaluating all device-related adverse events and device-related serious adverse events, and device deficiencies. This study was performed to comply with European Union Medical Device Regulation requirements with regards to implantable medical devices [13].

Mammotome® is aimed at developing products and technologies for breast cancer diagnostics. Mammotome® produces breast cancer biopsy Mammotome® markers (barrel, butterfly, open coil bowtie, triple twist, U-shape, barbell, tribell, and petite barbell) and North American distributor of the Magseed® magnetic marker. The common features include high visibility under all imaging modalities, compatibility with breast biopsy devices, direct puncture marking, anti-migration accuracy placement, and the simplification of surgery and therapy and their outcomes.
