MR-guidance for biopsy procedures features high intrinsic soft-tissue contrast. However, artifacts induced by the metallic needle can reduce the localization of the needle and require low susceptibility needle materials with poorer cutting performance. In this work, we explore 2D multi-spectral imaging (2DMSI) for reducing the needle artifacts for more precise needle localization and tracking or to enable the usage of conventional stainless-steel biopsy needles.
