International Workshop on Magnetic Particle Imaging

Magnetic Particle Imaging (MPI) is an emerging tracer-based imaging modality that uses static and time-varying magnetic fields to directly visualize the spatial distribution of superparamagnetic iron oxide nanoparticles (SPIONs). By exploiting their nonlinear magnetization response, MPI provides highly sensitive, quantitative imaging with no tissue background, no ionizing radiation, and high temporal resolution. Following two decades of predominantly preclinical development, MPI has recently reached a major translational milestone with the first in-vivo human studies. Current developments focus on human-scale and interventional MPI systems, improved tracer materials and reconstruction methods, as well as multimodal approaches combining MPI with anatomical imaging such as CT or MRI. Beyond vascular and lymphatic imaging, MPI offers considerable potential for inflammation and cancer imaging, cell tracking, perfusion and functional imaging, and image-guided interventions. Moreover, the combination of quantitative MPI with magnetic hyperthermia, targeted drug delivery, and other nanoparticle-based therapies is increasingly establishing MPI as a platform for image-guided theranostics.
