Gd(OH)3 nanorods, Gd(OH)3 nanoparticles, and Gd2O3 nanoparticles were prepared and their longitudinal water proton relaxivities (r1s) were investigated. They are important for application to a highly sensitive T1 MRI contrast agent. The r1s did not much depend on either composition or morphology but on particle diameter such that an optimal particle diameter (¡1.7 nm) exists for a maximal r1 (~ 15.2 s-1mM-1). This is interpreted such that surface Gd(III) ions mainly contribute to the r1.
