Effects of muscle fiber orientation to main magnetic field on muscle metabolite profiles for magnetic resonance spectroscopy acquisition

Figure 4 Metabolites identified by AMARES algorithm. Metabolites are shown in the following quantities: IMCL (CH₃) at 0.9 ppm, EMCL (CH₃) at 1.1 ppm, IMCL (CH₂) at 1.3 ppm, EMCL (CH₂) at 1.5 ppm, and creatine at 3.02 ppm. At 30°, 60°, and 90°, spectra were shown by a factor of 3.8. Spectrum of muscle positioned at 90° to the main magnetic field was unable to be identified for EMCL (CH₂) at 1.5 ppm. EMCL: Extramyocellular lipids; IMCL: Intramyocellular lipids.
