A stack of five 2D slices of the heart was acquired in a healthy volunteer using a diffusion weighted stimulated echo (STEAM) single shot EPI sequence, with a total acquisition time of 40 min. Images were post-processed to create whole heart helix angle fibre tractography maps and fractional anisotropy (FA) maps.
