  1. Group A received 0.10 mmol/kg, group B 0.15 mmol/kg, and group C 0.20 mmol/kg of gadobutrol. CNRscar-blood Contrast-to-noise ratio between myocardial scar and blood, CNRscar-rem Contrast-to-noise ratio between scarred and remote healthy myocardium, SNRinf Signal-to-noise ratio of the myocardial scar. Kruskal-Wallis and Fisher χ2 tests were used
