Figure 2.

Panel A shows a plot of data acquired from Intralipid over the TE range 2.3 to 11.5 ms. Best-fit curves to two models are shown, as described in the text: a broad fat peak containing two components (solid line) and a composite peak containing five components (dashed line). Panel B shows the same data set over a longer range of TE and best-fit curves to the two models. Panel C shows the 1%, 5%, 10% and 20% fat fractions estimated at different flip angles; overlaid are best-fit curves to the expected dependence due to T1 effects. Panel D shows the amplification factor A₁ (defined in Eq 9) and the best-fit curve to the data points.
