Metallic clip soft tissue markers are a promising alternative to wire-guided localization in localizing breast cancer for surgery. However, the metallic core in the marker creates magnetic field distortions with MRI, which leads to various artifacts including signal voids and failed chemical shift-based fat suppression. This work characterizes the effect of a soft tissue marker at 1.5T and 3.0T using conventional breast imaging sequences as well as multi-spectral sequences. Several fat suppression methods were also evaluated. Field distortions and imaging artifacts are similar at 1.5T and 3.0T, and can be addressed using multi-spectral methods and T1 based fat suppression.
