Transitioning From the Traditional Wire Localization to the Wireless Technology for Surgical Guidance at Lumpectomies: Part A. Radioseed Localization

Abstract

Iodine-125 (I-125) labelled radioactive seeds were the first published wireless pre-operative image-guided breast localization technique. Radioseeds offer benefit to radiologists as a relatively intuitive procedure with precise mammographic or sonographic-guided localization and improved patient experience. Localization and surgical dates can be uncoupled, which facilitates efficient scheduling for radiologists and surgeons. Surgeons can better tailor their surgery with intra-operative localization using a special probe to detect the emitted gamma energy. Due to radioactivity, implementation of a radioseed program requires compliance with the National Regulatory Commission and therefore multidisciplinary involvement. Seeds have a high placement success rate, and comparable surgical success and re-excision rate to wires.
