Abstract

An intracorporeal site marker has high ultrasound reflectivity, presents a substantial acoustic signature from a small marker, so as to avoid obscuring diagnostic tissue features in subsequent imaging studies, and can be readily distinguished from biological features. The biopsy site marker may include features to fix the marker to the biopsy site so as to resist migration from the biopsy cavity.
