Late Gadolinium Enhancement and myocardial T1 mapping are methods with distinct advantages for evaluation of myocardial scar and fibrosis. Conventionally these are performed as two separate sequences. Also T1 mapping is commonly performed by acquiring multiple 2D single-shot images during one breath-hold per slice. We propose a novel sequence for combined free-breathing 3D LGE and 3D T1 mapping. This allows efficient imaging by reusing the LGE data for T1 mapping. Furthermore it provides improved spatial coverage, higher resolution and higher signal-to-noise ratio compared to 2D imaging.
