Breast tissue markers
Breast tissue markers are a common finding in breast radiology. These are typically inserted following percutaneous biopsy, either under ultrasound or sterotactic guidance. They can be invaluable in identifying known benign areas or shrinking/treated malignant lesions on follow up imaging.
A number of various makers are in use including ribbon, coil and wing markers with easily differentiated appearances on mammograms. Some new markers are available with superior detection on ultrasound.
Markers can also be used to target intervention (localization wire targets) or with clips inserted peri-operatively to guide subsequent radiotherapy treatments.
