In this work, we demonstrate the feasibility of free-breathing whole-heart simultaneous bright-blood and black-blood imaging at 0.55T. We implemented an image navigator (iNAV)-based non-rigid motion-corrected 2 heartbeat sequence with 100% respiratory scan efficiency and high-dimensional patch-based low-rank (HD-PROST) denoising. The research sequence was validated on one healthy subject, showing simultaneous 3D visualization of cardiovascular anatomy on bright and black blood images at 0.55T in under 12 minutes scan time.
