Atrial fibrillation currently affects over 7 million people in the U.S. and Europe. Late Gadolinium Enhancement (LGE) imaging offers a means to assess ablation of the left atrium and the pulmonary vein ostia. Here we propose to reduce the scan time and improve the image quality over a standard 3D Cartesian acquisition (with respiratory and ECG gating) by (i) acquiring data using a stack of stars scheme and (ii) using compressed sensing reconstruction methods. Results from simulated phantom and patient data show the feasibility of the method to obtain better image quality that may improve clinical utility of LGE imaging.
