An accelerated self-gating (SG) technique, SparseSG, was developed to realize whole-heart coverage of 3D cardiac cine imaging at 3T without ECG and breath-holding. Preliminary in vivo study demonstrated that a whole heart coverage of 3D cine imaging can be achieved within 1 min and the technique had excellent performance compared to the standard ECG-triggering and conventional SG methods.
