Proton magnetic resonance spectroscopy in skeletal muscle: Experts' consensus recommendations

NMR Biomed. 2021 May;34(5):e4266. doi: 10.1002/nbm.4266. Epub 2020 Feb 5.

Abstract

1 H-MR spectroscopy of skeletal muscle provides insight into metabolism that is not available noninvasively by other methods. The recommendations given in this article are intended to guide those who have basic experience in general MRS to the special application of 1 H-MRS in skeletal muscle. The highly organized structure of skeletal muscle leads to effects that change spectral features far beyond simple peak heights, depending on the type and orientation of the muscle. Specific recommendations are given for the acquisition of three particular metabolites (intramyocellular lipids, carnosine and acetylcarnitine) and for preconditioning of experiments and instructions to study volunteers.

Keywords: acetylacarnitine; carnosine; deoxymyoglobine; intramyocellular lipids; lactate; magnetic resonance spectroscopy; physiology; skeletal muscle.
