Late Gadolinium Enhancement imaging of the left atrium is evolving as a valuable tool in the treatment and management of atrial fibrillation using radio-frequency ablation. Current segmented Cartesian acquisition scheme with a respiratory navigator based on the diaphragm position is limited in achieving consistent image quality. Here we explore an alternative self-navigated hybrid radial scheme that can identify motion and can offer improved image quality efficiently. The method is based on a more direct measurement of motion across different segments in 3D k-space and then using compressed sensing reconstruction to further improve the image quality. Results from patient studies show the feasibility of promising method.
