Magnetic Particle Imaging (MPI) for NMR and MRI researchers

► Magnetic Particle Imaging (MPI) is a new tracer imaging modality first presented in 2005. ► MPI employs iron oxide (SPIO) contrast agents for kidney-safe angiography. ► SPIOs in MPI generate positive, “bright blood” contrast, with no signal from tissue. ► MPI already achieves fast, high-contrast angiograms with millimeter-scale resolutions. ► MPI has great potential for stem cell tracking, cancer diagnosis, inflammation imaging.
