A perfluorocarbon emulsion was intravenously administered in ApoE-knockout mice. Next, fluorine-19 MRI was performed multiple times after injection in order to quantitatively determine the time course of perfluorocarbon uptake in regions where atherosclerotic plaques often occur. The signal-to-noise ratio (SNR) at these locations reached an optimum of ~10 at 6-8 days after injection.
