The aim of this study was to compare Dixon imaging and
single voxel spectroscopy (SVS) for determination of low
fat contents in muscles that are not prone to motion, as
shoulder muscles (infraspinatus and supraspinatus). The
results clearly demonstrate that also for low contents
below 10%, the lipid content can be determined reliably
by both, Dixon and SVS methods. This was shown by strong
correlations between results from SVS and Dixon and
between independent measures of right and left shoulders
and between the two different muscles investigated.
