Magnetically Directed Targeting Aggregation of Radiolabelled Ferrite Nanoparticles
Figure 3
Biodistribution and magnetically-derived biodistribution changes to the Tc-99m nanoferrite particles. Images were acquired at 5 and 15 min after injection from the tail vein of the rats, and the acquisition time was 60 seconds. (a) Biodistribution of the Tc-99m nanoferrite; (b) A magnet was placed over the right lower abdominal area of the rat before administration of Tc-99m nanoferrite; an area with increased radioactivity was demonstrated (arrows).
