Purpose To assess the agreement between published magnetic resonance imaging (MRI)-based regions of interest (ROI) sampling methods using liver mean proton density fat fraction (PDFF) as the referen...
For the quantitative MRI data, we estimated the proton density fat fraction (PDFF) and R2∗ from the single-slice liver multi-echo data by using the PRESCO (phase regularized estimation using smoothing and constrained optimization) algorithm.27 We converted R2∗ into iron concentration (mg/g...
