Objectives To evaluate breast biopsy marker migration in stereotactic core needle biopsy procedures and identify contributing factors. Methods This retrospective study analyzed 268 stereotactic biopsy markers placed in 263 consecutive patients undergoing stereotactic biopsies using 9G vacuum-assisted devices from August 2010-July 2013. Mammograms were reviewed and factors contributing to marker...
Objectives To develop a breast biopsy marker that resists fast and slow migration and has permanent visibility under commonly used imaging modalities. Methods A polymer-nanoparticle composite film was prepared by embedding superparamagnetic iron oxide nanoparticles and a superelastic Nitinol wire within a flexible polyethylene matrix. MRI, mammography, and ultrasound were used to visualize the marker...
