AIM: The aim of this study was to develop a marker clip for use in minimally invasive diagnostics of breast cancer that can be placed and visualized during ultrasonography, mammography, and magnetic resonance imaging. METHODS: The newly developed O-twist marker consists of three 0.15-mm biocompatible nitinol wires twisted together to form rings with a diameter of 2.5 mm. These are inserted elongated into a 20G cannula. The marker is ejected into the tissue through a mandrin and reverts to its predetermined ring form. RESULTS: The multiple curves of the surface render the marker highly visible. Its geometry permits secure anchorage even in larger biopsy cavities and additionally prevents migration within the tissue. CONCLUSION: The O-twist marker is applicable for all examination modalities and biopsy needles or biopsy systems and represents an important development for breast cancer diagnostics.
