Objective: The purposes of this study were to compile mammographic images in various projections showing commercially available breast biopsy site markers and to provide a standardized nomenclature and marker guide to improve physician communication and patient care.

Materials And Methods: A retrospective review of all breast biopsy markers encountered at one institution was conducted from January 2012 to January 2018. Markers placed at the facility and those placed at outside institutions with the patient subsequently referred to the study institution were included. Additional drawings and photographs and biopsy marker information were compiled from manufacturers and the literature. Intrinsic properties, features, pitfalls, and biopsy marker mimics were recorded from the institution's experience and the literature.

Results: Thirty-eight different biopsy marker shapes available from six manufacturers were identified, and mammograms of 37 were compiled and organized by manufacturer. Nomenclature was compiled on the basis of the manufacturer names of each marker. Potential pitfalls and mimics were identified. Manufacturer-reported marker material composition and carrier properties were summarized, including decreased marker migration, enhanced ultrasound visibility, and varying MRI susceptibility.

Conclusion: Variability in the appearance and nomenclature of breast biopsy site markers may contribute to misinterpretation, miscommunication, and possibly removal of the incorrect lesion. A comprehensive guide to breast biopsy marker nomenclature is clinically useful, and standardization is necessary.
