In this study, we demonstrate the feasibility of CINE fetal CMR at 0.55 T at multiple spatial resolutions. First, real-time images are reconstructed for motion-correction and cardiac gating. Fetal cardiac CINEs are then reconstructed using the corrected data. Retrospective CINEs have higher SNR relative to their corresponding real-time reconstructions. Feasibility of the pipeline is demonstrated for up to 1.0 mm in-plane resolution. Good cardiac structure conspicuity is observed at coarse spatial resolutions in real-times and at all spatial resolutions in CINEs.
