Given the thin nature of the left atrial (LA) wall (1-3 mm) and the need to perform respiratory gating with navigator echoes, the clinical translation of LA late gadolinium-enhanced (LGE) MRI has proven difficult. This study describes a self-navigated, free-breathing 3D LA LGE pulse sequence with stack-of-stars k-space sampling and GRASP reconstruction. This study shows initial experience in quantifying LA fibrosis in patients with atrial fibrillation undergoing ablation therapy.
