From: A pilot study of leakage and compartmentalization of the contrast agent Ablavar
Myocardium longitudinal relaxation rates R1 as a function of blood longitudinal relaxation rates for Ablavar in healthy volunteers displays the same linear relationship as an extracellular agent. In comparison, intravascular USPIO agents feruglose and ferumoxytol display a non-linear trend. Ferumoxytol data is within the bounds predicted by the slow and fast exchange limits of the two compartment model.
