Abstract
Background The assessment of myocardial infarction (MI) heterogeneity using late Gadolinium enhancement (LGE) MRI has been limited to static analysis at single late postinjection time. We developed a rapid single breath-hold LGE MRI method using a novel parallel imaging accelerated 3D spiral acquisition. We propose to use this technique to capture temporal variation in scar enhancement at early to late post-injection times, termed early-to-late Gadolinium enhancement (ELGE) MRI.

Starting at 1 or 2 minutes after contrast administration, the 3D ELGE imaging was performed every minute until 10 minutes post injection
