3D MPI scans of excised organs, displayed as MIPs. (a) Organs excised from animal injected with 700,000 MAA-SPIOs, and approximately 1.4×105 SPIO particles per MAA cluster (0.4 mg Fe/kg), and sacrificed 10 minutes after injection. (b) Organs excised from animal injected with SPIOs only (0.4 mg Fe/kg) and sacrificed 10 minutes after injection. Colorbar in µg Fe/cm3.
