1H MRS spectra of lipids. (A) High‐resolution proton spectrum of soybean oil acquired at 7 T. Resonances are assigned to protons of fatty acid chains and glycerol as indicated. (B) Orientation dependence in a model of intralipid (spherical vesicles) and soy bean oil (cylindrical‐shaped vial) acquired at 4.7 T. Relative angle in respect to B0 magnetic field is given in degrees. (C) Orientation dependence in human muscle (m. tibialis anterior), acquired on 1.5 T (PRESS, TE 20 ms, TR 3000 ms); the position of EMCL methylene resonance is dependent on the angle between the muscle and B0 magnetic field, which is given in degrees.
