Using a fibrin-binding peptide (FibPep) radiolabelled with 111In, Starmans et al. demonstrated the successful location of thrombi in the carotid artery of an acute murine thrombosis model using SPECT (Starmans et al., 2013). In the same animal model, the group also demonstrated significantly increased thrombus uptake when they injected iron oxide nanoparticle-micelles, which were conjugated with Fibpep, via magnetic particle imaging (Starmans et al., 2015).
