The efficacy of the nanoparticles for image contrast enhancement was evaluated by fluorescence imaging in nude mice, and by MRI in rats. The agents proved effective in both modalities. Postmortem ICP-MS showed the biodisttibution to be essentially limited to the kidneys and the urine of the rat 3 h after injection. The question of long-term release of Gd " " ions from residual particles was not addressed.

Then, an image contrast enhancement step is accurately performed on each gray retinal image Iq to produce two pairs of contrast-enhanced images for every retinal one.
