Characterization of Resovist® Nanoparticles for Magnetic Particle Imaging
This study investigates the dynamic magnetic properties of Resovist® for magnetic particle imaging (MPI) utilizing static M-H, ac susceptibility (ACS) and magnetic particle spectroscopy (MPS) measurements on a Resovist® suspension and an immobilized sample. Investigating the magnetic moment and anisotropy energy barrier distributions in the sample as well as the relationship between them, we clarified that the MNPs with large magnetic moment (10− 24~10− 23 Wb·m) and small anisotropy energy barrier play an important role in MPI.
