Measurements were performed in two different experimental coil settings: first with a novel gradiometer providing three orthogonal channels and second a single-channel gradiometer at varying gradient strengths. The volumes were calculated using two different approaches: a calibration approach based on the amount of SPIOs and a threshold approach. We show that with both approaches MPI volumetry is feasible. Finally we present initial in vivo results of a retrograde voiding cystography in rats.en2365-903320202, Suppl 113Infinite Science Publishinghttps://creativecommons.org/licenses/by/4.0/InformatikMedizinJournal Article10.15480/882.442810.18416/IJMPI.2020.200905710.15480/882.4428Journal Article
