Two self-gating approaches to reconstruct free-breathing cardiovascular image generated by Golden Angle radial trajectory MRI were compared. The results show that both central k-space magnitude and phase self-gated image have comparable quality with breathhold Cartesian CINE image, and the phase self-gating signal is less sensitive to the coil sensitivity compared to the magnitude based self-gating signal.
