A highly accelerated 100% scan efficiency reconstruction approach for whole-heart coronary MRA is proposed. This approach achieves 100% scan efficiency by estimating the motion from an interleaved golden radial image navigator. Further acceleration is achieved by undersampling the MRA acquisition using a golden-step spiral-like Cartesian acquisition and the low dimensional structure self-learning and thresholding (LOST) reconstruction. This LOST-motion corrected approach leads to slightly reduced image quality in comparison to that of an ~8 times longer scan time navigator-gated approach.
