NMR Transversal Relaxivity of Suspensions of Lanthanide Oxide Nanoparticles
Norek, Małgorzata; Pereira, Giovannia A.; Geraldes, Carlos F. G. C.; Denkova, Antonia; Zhou, Wuzong; Peters, Joop A.Aqueous suspensions of paramagnetic lanthanide oxide nanoparticles have been studied by NMR relaxometry. The observed relaxivities are explained by the static dephasing regime (SDR) theory. The corresponding R2 relaxivities are considerably smaller and are strongly dependent on the interval between the two refocusing pulses. The experimental data are rationalized by assuming the value of the diffusion correlat...
