Relationship of acquisition timing post GBCA administration and signal/contrast-to-noise ratios. (Top left) apparent blood pool signal-to-noise ratio (SNR), (top right) apparent scar SNR, (bottom left) apparent scar to blood pool contrast-to-noise ratio, and (bottom right) LA scar area as a percentage of left atrium, thresholded at 3.3 standard deviations above blood pool mean. Values presented are for standard acquisition parameters only (n = 49 at each time point). For each plot, 3 p-values are presented: the top is p-value for Friedman test, assessing overall impact of time, and the bottom two are the p-values for Wilcoxon matched-pairs signed rank test
