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.
