A respiratory self-navigated 3D whole-heart technique was extended to inversion-recovery for 3D late gadolinium enhancement (LGE) imaging and integrated into a dedicated protocol where the same sequence was acquired also pre-contrast and during slow infusion, with T2 preparation, for comparison. Signal and contrast to noise, as well as vessel length and sharpness increased in the slow infusion datasets, while the 3D LGE datasets allow for combined coronary tree and scar tissue visualization in one single acquisition. The 3D LGE dataset can also be reformatted for color-coded 3D visualization and might be useful for planning ablation as part of re-synchronization procedures.
