3D late gadolinium enhanced (LGE) imaging is a promising technique for the non-invasive assessment of atrial fibrosis. In order to minimize respiratory motion, current 3D LGE atrial imaging relies on diaphragmatic navigator gating, leading to time-consuming scans with unpredictable duration. Here we introduce a highly efficient respiratory motion-compensated 3D water/fat IR-prepared LGE atrial imaging protocol with predictable scan time. Preliminary results demonstrate that the proposed approach enables depiction of atrial scar comparable to conventional 3D atrial LGE imaging, but with a significantly shorter scan time of <5 minutes. The proposed approach holds promise for high-resolution atrial wall imaging.
