Background

Cardiac magnetic resonance (CMR) imaging using phase sensitive inversion recovery (PSIR) late gadolinium enhancement (LGE) is the in vivo reference standard for assessing focal myocardial scar. Post-contrast T1-mapping by Modified Look-Locker Inversion recovery (MOLLI) can be used to generate a Synthetic PSIR LGE (SynLGE) image with an image contrast similar to conventional LGE images. We aimed to identify focal myocardial scar by SynLGE and compare its diagnostic accuracy with the reference standard LGE. We hypothesized that SynLGE has an accuracy which approaches LGE for diagnosing focal myocardial scar.
