1. A biopsy site marker comprising:
- a first marker element configured for detection by a first imaging modality, wherein the first marker element is a non-absorbable cylinder;
a second marker element configured for detection by a second imaging modality different from the first imaging modality, wherein the second marker element is a non-absorbable wire having a first helical shape positioned around a longitudinal extent of the non-absorbable cylinder of the first marker element; and
a third marker element having a second helical shape overlapped with the first helical shape and positioned around a longitudinal extent of the non-absorbable cylinder of the first marker element.

Abstract
A biopsy site marker is disclosed. The biopsy site marker includes a first marker element and a second marker element. The first marker element is configured for detection by a first imaging modality. The second marker element is configured for detection by a second imaging modality different from the first imaging modality. The second marker element may be a non-absorbable wire having a predetermined shape and is substantially engaged with the first marker element.
