1H MRS offers unique insights into hepatic lipid composition. In this study, NAFLD patients with and without Type 2 Diabetes were scanned and hepatic lipid composition indices measured. Diabetic patients then underwent a randomized controlled trial to investigate the effectiveness of 6 weeks moderate exercise vs control. Lipid composition indices were similar to previous studies in obesity, and show no differences in diabetic v non-diabetic groups. The intervention also shows no change in hepatic fat fraction or lipid composition.
