Keywords: Heart, SusceptibilityCardiac Quantitative Susceptibility Mapping (QSM) is a promising technique for the evaluation of iron levels in the myocardium, particularly after a hemorrhagic infarction. In this abstract, we validate the accuracy of our QSM acquisition and reconstruction procedure in phantom experiments, and characterize its precision and repeatability in the myocardium in a healthy volunteer cohort. We found a strong linear relationship between the gadolinium concentration and measured susceptibility in the phantom. In vivo QSM precision and repeatability in the myocardium were 0.11±0.05 ppm and 0.02±0.02 ppm, respectively.
