Free-breathing cardiac cine imaging is desirable for improving patient experience, expanding CMR eligibility, achieving robust image quality for uncooperative subjects, and simplifying CMR workflow. In this work, we propose a prototype technique, RTCSCineMoCo, that combines highly accelerated real-time acquisition, compressed sensing reconstruction, and retrospective, fully automated respiratory motion correction. In a preliminary evaluation on four volunteers, RTCSCineMoCo achieved similar spatiotemporal resolution, visually comparable image quality, and consistent LV function parameters as the reference breath-hold technique. RTCSCineMoCo is a promising option for free-breathing cardiac cine imaging, and further studies are warranted to evaluate its feasibility and utility in a clinical setting.
