Dynamic inversion time for improved 3D late gadolinium enhancement imaging in patients with atrial fibrillation

High resolution three‐dimensional (3D) late gadolinium enhancement (LGE) imaging is performed with single R‐wave gating to minimize lengthy acquisition durations. In patients with atrial fibrillation (AF), heart rate variability results in variable magnetization recovery between sequence repeats, and image quality is often poor. In this study, we implemented and tested a dynamic inversion time (dynamic‐TI) scheme designed to reduce sequence sensitivity to heart rate variations.
