| Zusammenfassung | The here presented study investigated the influence of magnetic particle-particle interactions within the MPI tracer on the imaging performance of the tracers. To realize a proper separation and to increase the distances between the individual magnetic nanoparticles (MNP) within the tracer (which results in reduced particle-particle interactions), the MNP were diluted by non-magnetic SiO2 spacers in the nanometer range. The obtained MNP/SiO2 mixtures were characterized and used to build up measurement phantoms by embedding the mixture into a long-term stable polymer matrix. In MPS and MPI measurements it was found that reduction of the magnetic interactions encompassed by increasing the MNP distances leads for the tested tracer system to a weaker decrease of higher harmonics in the MPS spectra after immobilization of the particles and thereby, a higher spatial MPI resolution can be achieved. |
