Abstract

The experimental transverse relaxivity r2,exp of protons in water suspensions of spherical SiO2 shelled γ Fe2O3 nanoparticle clusters of different sizes is analyzed based on existing models. It is shown that r2,exp can be significantly larger than the modelling relaxivity, which may be attributed to nanosphere aggregations. © 2011 Elsevier B.V.
