Synopsis
Keywords: Interventional Devices, MR-Guided InterventionsIn this work we report initial results evaluating the imaging artifacts associated with different candidate materials for use in needle-based interventions. The impact of each material was assessed using MRT and DWI ADC as well as compared with local Bo field maps.
