Mean SNR amplitudes and FWHM of unsuppressed water peak at 3.0T and 1.5T.

SNR
FWHM (Hz)
3.0T 1.5T %-chg 3.0T 1.5T %-chg
Soleus 340.5 ± 4.5 * 247.3 ± 6.5 64 14.2 ± 0.3 * 11.9 ± 0.3 19
Tibialis anterior 379.4 ± 1.2 * 250.4 ± 4.9 62 13.4 ± 0.3 † 12.5 ± 0.3 7

Data are mean values ± standard errors of the mean.

SNR, signal-to-noise ratio; FWHM, full-width at half maximum; Hz, Hertz.

%

-chg, percent change from 1.5T to 3.0T [for SNR, percent change was calculated from SNR area (mean SNR amplitude × mean FWHM)].
