Using a 16-element receive array at 7T permitted precise
metabolite ratios from the whole liver, in a study on 5
normal volunteers. A 3D UTE-CSI sequence gave an average
of 27 voxels (each 6.3mL nominal volume) of high quality
data for each subject. The inter-subject mean and SD of
the metabolite ratios (averaged over all voxels) were
then calculated: 36.4 6.94 for PME/PDE, 44.4 3.93
for GPC/Total Ester and 12.6 3.58 for PE/Total Ester.
This preliminary work will inform the design of future
clinical studies of diseases such as non-alcoholic fatty
