MPI images of rats injected with Ferucarbotran (top) and LS-008 (bottom) overlaid onto projection X-ray images for anatomical reference. Both tracers were injected at a dose of 5 mg of Fe / kg. MPI images show slow clearance of the tracer by the liver and spleen of a rat over a 70 day period. Ferucarbotran is predominantly cleared by the liver, while Ls-008 is predominantly cleared by the spleen.
