Box plots of signal-to-noise ratio of the scarred myocardium (SNRscar), contrast-to-noise ratio between infarcted and remote myocardium (CNRscar-rem), and contrast-to-noise ratio between infarcted myocardium and blood (CNRscar-blood) in the three groups being administered 0.10 (group A), 0.15 (group B), and 0.20 (group C) mmol/kg of gadobutrol. Significant differences between groups are indicated with an asterisk (*), and red crosses (+) indicate outliers. In particular, SNRscar was lower in group A (46.4 IQR 40.3–65.1) than in both group B (70.1 IQR 52.2–111.5, p = 0.013) and group C (72.1 IQR 59.4–100.0, p = 0.002), and CNRscar-rem was lower in group A (62.9 IQR 52.2–87.4) than in both group B (96.5 IQR 73.1–152.8, p = 0.008) and group C (103.9 IQR 83.9–132.0, p = 0.001). There were no other significant differences in SNRscar, CNRscar-rem, or CNRscar-blood (p ≥ 0.335)
