?:definition
  • Needles designed for localization of lesions, especially tumors, in thoracic breast tissue. These devices typically consist of 20-gauge, hollow needles with marks to facilitate accurate depth placement. Most needles include a strong, flexible localization wire that can be retracted and repositioned; they may also include a locking mechanism to prevent wire migration during breast compression or patient transport. Breast lesion localization needles are available in several lengths (e.g., 3, 5, 12.5 cm). Some needles include tips that can be easily visualized using ultrasonic imaging equipment (i.e., echogenic tips) to facilitate the procedure.
