FIG. 2.

a: Fat signal fraction in the presence of ${\mathit{\text{T}}}_2^{\ast }$ effects with $T_{2\text{w}}^{\ast }=T_{2\text{f}}^{\ast }=30\text{ms}$. The effects lead to 2% of bias at the true fat fraction = 0. b: Simulated fat fraction after ${\mathit{\text{T}}}_2^{\ast }$ correction (i.e., Eq. 5) with ${\mathit{\text{T}}}_{2\text{w}}^{\ast }=30\text{ms}$, and ${\mathit{\text{T}}}_{2\text{f}}^{\ast }$ varies from 10 ms to 60 ms. The correction was performed using 30 ms to correct for both the water and fat signals. Assuming the true fat fraction is 1% (point as the dotted lines crossed, where ${\mathit{\text{T}}}_2^{\ast }$ corrected fat fraction is also 1%), the deviation from true value is less than 0.04% in the worst case.
