MDMing DengZLZhen LiLSLi Sun

Key Points

  • Diabetes risk is predicted by liver proton density fat fraction, emphasizing its potential to identify at-risk individuals.
  • Liver enzymes mediate the relationship between proton density fat fraction and dysglycemia, supporting metabolic health monitoring.
  • Observational analysis correlates liver MRI-derived values with diabetes outcomes in patients with obesity, demonstrating clinical relevance.
  • These findings highlight the potential of liver fat measurements in assessing diabetes risk in obese populations.

Abstract

The liver MRI–derived proton density fat fraction (PDFF) independently predicted prediabetes and diabetes risk in patients with obesity, and the liver PDFF–dysglycemia relationship was partially mediated by liver enzymes.
