<b>Metallic Marker Placement After Stereotactic Core Biopsy of Breast Calcifications:</b>Comparison of Two Clips and Deployment Techniques

Abstract

A vascular ligating clip delivered to a stereotactic core biopsy site by an 18-gauge spinal needle is comparable in apparent accuracy and stability to a clip deployed through an 11-gauge probe. This technique allows core biopsies to be performed with instruments smaller than 11-gauge and at a 40% savings in equipment cost.
