The aim of this study was to compare fat quantification
determined by Dixon MRI, SVS and CSI in a back muscle
(psoas major) in healthy subjects for small amounts of
lipids only. A strong correlation was obtained for SVS
and CSI results, but spectroscopy results didn't
significantly correlate with Dixon results. Back muscle
low fat content quantification can reliably be
quantified by spectroscopy MR techniques (SVS and CSI),
while noise and artefacts limit the preciseness of Dixon
MRI for low fat quantification.
