Grey-blood phase-sensitive inversion-recovery (PSIR) late gadolinium enhancement (LGE) imaging has shown promising and robust results for the assessment of myocardium viability. Conventionally 2D grey-blood LGE images are acquired under several breath-holds in different image orientations to depict scar extension. However, these approaches achieve limited spatial resolution and coverage and can be challenging in un-collaborative patients. In this work, we have proposed a free-breathing 3D whole-heart LGE sequence with water/fat Dixon encoding and blood nulling which provides grey-blood PSIR images with isotropic resolution for scar visualization and complementary 3D fat images for pericardial and myocardial adipose tissue detection in ~6min.
