Late gadolinium enhancement (LGE) MRI often suffers from poor scar-to-blood contrast when used for detection of (sub)endocardial scar due to the bright signal of adjacent blood. We sought to validate a novel dark-blood LGE technique in a large cohort of 250 patients at both 1.5T and 3T. Combining left ventricular blood nulling with phase-sensitive inversion-recovery significantly improved both image quality and diagnostic confidence compared to conventional bright-blood LGE. As no additional magnetization preparation is used, clinical application on current MRI systems is readily available without the need for extensive simulations, software modifications and/or additional training.
