The objective of this study was to evaluate the potential of a high-relaxivity macromolecular gadolinium (Gd) chelate to target folate receptors (FRs). P866 is a dimeric high-relaxivity Gd chelate coupled to a folate moiety. Binding affinity, in vivo biodistribution studies in KB tumor-bearing mice at 1, 4, and 24 h, and dynamic contrast-enhanced (DCE)-MRI(More)
Ultrasmall superparamagnetic iron oxide (USPIO) particles are efficient contrast agents used in vivo to enhance relaxation differences between healthy and pathological tissues. Detailed understanding of their physicochemical properties in suspension is necessary to guarantee the quality and safety of biological USPIO particles application. The ferrofluids(More)
Ultrasmall superparamagnetic iron oxide (USPIO) particles are maghemite or magnetite nanoparticles currently used as contrast agent in magnetic resonance imaging. The coatings surrounding the USPIO inorganic core play a major role in both the in vitro stability and, over all, USPIO's in vivo fate. Different physicochemical properties such as final size,(More)
