Outline of Final Research Achievements

The aim of this study was to investigate the association between the ectopic fat tissue of skeletal muscle, liver, and pancreas in non-alcoholic fatty liver disease (NAFLD) patients by proton density fat fraction (PDFF) using 3T MRI. There were statistically significant differences in PDFF measurements of skeletal muscle, liver, and pancreas among three groups. With the PDFF measurements of skeletal muscle, there was statistically significant difference between NAFLD with DM group and NAFLD without DM group. For predicting NAFLD with DM, ROC analysis revealed that muscle-FF was the most useful parameter (AUC=0.83) and at a cutoff-value of 4 and over, sensitivity, specificity, PPV and NPV were 82%, 75%, 70%, and 86%, respectively. There was a close association between the ectopic fat tissue of skeletal muscle that was quantified by 3T MRI-PDFF and co-morbid diabetes mellitus of NAFLD. Evaluation of ectopic fat tissue by 3T MRI-PDFF can be used to predict the advance of fat metabolism.
