Cardiac and respiratory triggered 2D PRESS echo-planar spectroscopic imaging with high spatial resolution was used for the assessment of triglyceride content in the human myocardium. The PRESS volume of interest selection enables smaller field of view and minimizes signal contamination from outside the PRESS box. The proposed data processing approach using magnitude spectra avoids the need for individual phase correction before voxel spectra averaging. High spatial resolution enables evaluation the local triglyceride changes in non-continuous and irregularly shaped volumes of interest.
