Figure 1From: Molecular MRI of myocardial peroxidase activity in ischemic injury reveals a chemical milieu incompatible with stem cell survivalMolecular MRI of Gd-MPO activation in vivo. A. Inversion recovery image 2 hours after probe injection. Unbound Gd has been washed out but activated probe is retained in the ischemic myocardium. B. R1 map of the same slice. C. Quantitative map of Gd-MPO concentration and activity in vivo.Back to article page
