This study introduces a free-breathing 3D whole-heart sequence with image-based navigation for post-contrast phase sensitive inversion recovery (PSIR) allowing for simultaneous bright-blood coronary angiography and black-blood late gadolinium enhancement (LGE) imaging. Such approach was successfully tested in a cohort of 10 patients with cardiovascular disease. Data acquisition was performed in free-breathing with 100% scan efficiency, thus allowing for predictable scan time. The proposed sequence allowed for LGE visualization with high volumetric coverage and improved contrast (black-blood dataset) while simultaneously providing sharp visualization of the coronary arteries and heart anatomy (bright-blood dataset).
