Spectroscopic imaging could provide insights into regional cardiac triglyceride variations, but scan times are relatively long. In this work metabolite-cycled echo-planar spectroscopic imaging with motion-adapted gating and weighted acquisition is proposed to assess triglyceride-to-water ratios in different regions of the human heart. Results are compared to metabolite-cycled EPSI with conventional acquisition and to single voxel measurements in the interventricular septum. It is shown that scan time can be reduced by more than half to less than 10 minutes as compared to conventional acquisition, while keeping the quality of triglyceride fitting constant.
