Statistical analyses of signal intensity variation over a cardiac cycle. (A) Cumulative density function of normalized intensity (NI) values (divided by minimum intensity for a given ROI for that subject) of myocardium (mean over all 23 subjects). (B) Distribution of ratio of 95th to 5th percentile NI for liver, myocardium and blood to myocardial contrast across subjects. (C) Percentage of cardiac cycle spent below the 1.1 times the mode value of the intensity over cardiac cycle for liver and myocardium. Plot B depicts the extent of myocardial signal variation in comparison to the contrast ration between blood and myocardium. Plot C depicts the percentage of cardiac cycle spent in steady state by the liver and myocardium.
