Magnetic particle imaging of size-isolated SPION. a Key MPI parameters including normalized signal-to-noise ratios (SNR) of the samples at the 4th harmonic of the MPI drive field as well as full width at half maximum (FWHM) measurements and hysteresis loss analyses of the samples were obtained using magnetic particle spectroscopy (MPS; which is comparable to a zero-dimensional MPI acquisition without the superimposed gradient field measurements). b MPI images reconstructed based on “E” shaped phantoms filled with the crude sample, C2 and Resovist®. c The intensity line profiles of the red marked lines through the phantoms in b are shown. The line profiles show the voxel intensity along the marked line and demonstrate a doubling of signal intensity for C2 in comparison to Resovist®
