(a) A plot with FF measurements at 3-T (black squares) and 1.5-T (black circles) plotted against the fat fraction by volume for the phantom experiments. The solid and dashed lines represent lines of regression at 3-T and 1.5-T respectively; (b) a plot of FF measurements from 3-T and 1.5-T against each other for the phantom experiments. The measurements were highly correlated (r = 0.98). The dashed line indicates perfect agreement. The intercept for the trend line (black) is shown.
