Motion is a key limiting factor in fetal cardiac MRI as the small, rapidly beating heart is subject to various periodic and spontaneous motions. Highly accelerated real-time imaging with high temporal resolution was used to obtain serial ‘snapshots’ of the fetal heart and surrounding anatomy that could be motion-corrected and reassembled, combining several cardiac cycles into a single heartbeat. A super-resolution reconstruction was applied to increase the visibility of dynamic anatomical features in the densely sampled data. The resulting cine images provide a clear depiction of dynamic cardiac features.
