Magnetic Particle Imaging (MPI) is an emerging molecular imaging modality that measures the location and concentration of superparamagnetic nanoparticle tracers in vivo (typically Iron Oxide, SPIOs) by detecting their response to spatially dependent magnetic fields. The technology is used in various research projects with focus on cell tracking, targeted imaging in cancer and neuroscience, angiogenesis/vascularity quantification as well as in the development of MPI tracer technology to leverage the translational potential of the technology.
