A safe and reliable method for localising interventional devices is being developed to facilitate MR guided vascular intervention, which has valuable attributes (e.g. reduced radiation dose, functional information, high soft tissue contrast, and generally no need for contrast agents). The proposed device localisation aproach is based on biocompatible iron-platinum alloy (FePt) nanoparticles in a polymeric matrix and has been applied to a novel MR safe guidewire.
