A STEAM single shot EPI sequence with two ECG triggers and respiratory motion correction was applied on the heart of a healthy volunteer to detect the cardiac fibre tracts. This method provides a useful tool to depict the myocardial structure under free breathing and may help us understand structural correlates of functional remodeling after heart disease.
