A technique is introduced using post-contrast cardiac Magnetic Resonance Fingerprinting (MRF) T1 and T2 maps to calculate synthetic late gadolinium enhancement (LGE) images with multiple contrast weightings, including bright-blood magnitude inversion recovery images, dark-blood T2-prepared inversion recovery images, and a novel contrast weighting (optimized for each patient) designed to improve differentiation among viable myocardium, blood, and scar based on measured T1 and T2 values. Initial results are presented in fifteen patients with ischemic cardiomyopathy scanned at 1.5T using conventional LGE and MRF-derived multi-contrast LGE images.
