Fig. 4

Dixon fat fraction map without (top) and with (bottom) segmentation of IMAT and muscle tissue. Left: high resolution (in plane pixel size x slice thickness - 0.98 ​× ​0.98 ​× ​3.0 ​mm3); center: standard resolution (1.56 ​× ​1.56 ​× ​3.0 ​mm3); right: same resolution as center but muscle tissue peeled by one voxel. The figure shows one slice out of 29 of the acquired 3D dataset. Results of the complete dataset for muscle tissue (MT) volume and proton density fat fraction (PDFF) depend on spatial resolution and on segmentation technique. Left: MT vol ​= ​985 ​cm³, PDFF ​= ​8.7%; center: MT vol ​= ​923 ​cm³, PDFF ​= ​13.2%; right: MT vol ​= ​500 ​cm³, PDFF ​= ​10.2%.
