Phantoms
that simulate the iron in tissue have been measured using a theoretical model
that can separately quantify dispersed (ferritin-like) and aggregated
(hemosiderin-like) iron using multiple spin echo (MSE) based R2 images. Here,
we examine a large range of these heterogeneous phantoms and a preliminary
patient population to determine the effects of stimulated echo (STE)
contamination in MSE sequences on the iron quantification.
