Cardiac magnetic resonance imaging provides a lot of physiological information about myocardial pathology, and the mDixon technique also has been developed on cardiac application recently. The fat deposition in myocardium is possibly related with cardiomyopathy, so it is important to determine the fat composition of myocardium. The mDixon provides an easy way to acquire such this information within one breath hold, and it has a consistent result with magnetic resonance spectroscopy from the previous study. Also it has been reported that multipeak fat spectrum model gives more robustness, and 7-peaks model is used in this study. The aim of this study is to evaluate fat fraction of myocardium with 7-peaks model.
