Tissue marking clips are commonly used to indicate the biopsy site as part of image guided breast procedures. Biopsy cavity marking facilitates future preoperative needle localization and identification of subtle or completely excised lesions. We review the distinct properties of 6 available marker clips manufactured by SenoRx (GelMark, Gel Mark Ultra and Ultracor), Inrad (Inrad), Ethicon Endo-Surgery, Inc. (Micromark) and Artemis (Mammomark). Each was imaged with a GE full-field digital mammographic unit, an Advanced Technology Laboratories HDI 5000 ultrasound unit with SonoCT, and with a 1.5T Seimens Sonata MRI system with clips embedded in a suitable gel phantom. Their distinct appearances in each modality were compared with size, shape and composition. The degree of MR generated artifact was examined with 2D and 3D imaging with spin echo and gradient echo pulse sequences. This comprehensive comparison of the appearance and artifacts of commonly used breast biopsy marker clips is clinically relevant to breast imagers for the care of patients undergoing diagnostic and image guided MR procedures.
To describe the appearance and quantify the artifacts of breast biopsy marking clips in mammographic, sonographic and MR imaging.
