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

Figure 1 Chicken’s extensor iliotibialis was used to perform muscle quantification for muscle metabolites by proton magnetic resonance spectroscopy. A: Skinned chicken thigh showing the extensor iliotibialis lateralis muscle fiber orientation (in the yellow marked area) at various angles (0°, 30°, 60°, and 90°) with regard to the main magnetic field (B₀); B: T2-weighted turbo spin echo MRI images show areas of proton magnetic resonance spectroscopy voxel placement. B₀: Main magnetic field direction.
