Fetal cardiac MRI may be a useful compliment to echocardiography given its ability to measure blood flow and produce quality images independent of body habitus. Fetal cardiac MRI is, however, technically challenging since the fetal electrocardiogram signal cannot be sampled for cardiac gating. Self-gating is a method to extract the cardiac gating signal directly from MRI data, and its performance has been validated on adults. In this work, we investigated the feasibility of using self-gating for fetal cardiac MRI and show the results from three pregnant volunteers.
