Fat infiltration in the myocardium is of great clinical interest as potential predictor of poor prognosis in patients with either ischemic or non-ischemic cardiac diseases. Commonly, 2D chemical shift encoded MR methods are used to obtain fat-water separated images. Nevertheless, fat infiltrations are often small and hence could be missed due to poor slice resolution. Here we propose a free-breathing 3D whole-heart fat-water imaging approach with an isotropic resolution of 1.5mm3, which uses respiratory motion correction and retrospective cardiac gating. The approach was evaluated in five patients demonstrating accurate visualisation of the heart and small fat infiltrations in the myocardium.
