Sources of Systematic Error in Proton Density Fat Fraction (PDFF) Quantification in the Liver Evaluated From Magnitude Images With Different Numbersof Echoes

The purpose of this work was to investigate sources of bias in MRI liver fat quantification that leads to a dependence of the proton density fat fraction (PDFF) on number of echoes. This was a retrospective analysis of liver MRI data from 463 subjects. The magnitude signal variation with echo time f...
