T1 bias in chemical shift-encoded liver fat-fraction: Role of the flip angle

Purpose To investigate flip angle (FA)‐dependent T1 bias in chemical shift‐encoded fat‐fraction (FF) and to evaluate a strategy for correcting this bias to achieve accurate MRI‐based estimates of liver fat with optimized signal‐to‐noise ratio (SNR). Materials and Methods Thirty‐three obese patients,...
