Myocardial CMR spectroscopy. A 2 × 2 × 1-cm3 spectroscopic volume was acquired from the interventricular septum during the systolic phase (left upper inset) to generate an input spectrum (left lower inset). 1H-CMR spectra were fitted and analyzed using the LC Model software (Provencher, Ontario, CA, USA). We quantified the total myocardial TG resonance as well as its components – including fatty acids (FA, lipid resonances δ 0.9, 1.3, and 1.6 ppm) and unsaturated fatty acids (UFA, lipid resonance δ 2.1 and 2.3, 2.8, 5.3 ppm).
