With recent advances in pulse sequence design, the assessment of myocardial triglyceride content by means of 2D spectroscopic imaging techniques has become possible. In the present work, the feasibility of whole-heart 3D spectroscopic imaging is investigated. By replacing signal averaging by a third phase-encoding direction volumetric spectroscopic data are acquired in the beating heart. It is demonstrated that navigated, local-look spectroscopic imaging is feasible and permits mapping of spatial distributions
