Table 2.

Correlation coefficients between simulation and the CRLB in a fat-water signal over multiple echo-train lengths. As with the one-peak (water only) signal, the uncertainties in chemical shift and amplitude have a high correlation with the CRLB for both water and fat. The uncertainties in $T_2^{*}$ correlate less with the CRLB as the number of echoes decreases.
