Besides
the total amount of adipose tissue, its distribution has recently been
recognized as an important factor in the pathogenesis of metabolic diseases
like diabetes mellitus. MRI is capable for space-resolved imaging of fat
distributions in the human body. In this study, we present a fully automatic
algorithm for fat quantification in MRI two-point Dixon data which considers
partial volume effects of fat voxels, compensates B1-inhomogeneities in the
MR images and separates subcutaneous and inner fat in the abdomen. MR
quantification results were compared to air-displacement plethysmography
measurements, which served as the standard of reference.
