The goal of this effort was to develop an intuitive, but physiologically meaningful method for quantifying myocardial perfusion by CMRI and to test the method on a dog model of Duchenne Muscular Dystrophy (DMD). The perfusion model characterized contrast kinetics using parametric maps of agent uptake and retention. Both parameters appeared to be altered in dogs with DMD compared to normal controls.
