Abstract

Superparamagnetic iron oxide particles in Resovist and SH U555C, used as magnetic resonance imaging contrast agents, are polydispersed and covered with a thick organic coating so that the average particle sizes are described with different definitions. The studies have shown that the transverse relaxation rate behavior is determined by the diameter of bare single-crystal magnetic particles having the particle-volume-weighted average volume and is affected by their thick organic coating.
