Briefly Noted: Progression of Fatty Liver Disease on MRI

M Mouzaki  et al. J Pediatr 2018; 201: 86-92. This study with 65 patients evaluated nonalcoholic fatty liver disease (NAFLD) progression between two MRI studies, with a median time span of 27 months.

Key findings:

  • There was no correlation between change in liver stiffness and change in ALT; there was a weak correlation between ALT change and fat fraction.
  • MRI fat fraction and stiffness decreased in 29% and 20% of patients respectively and increase in 25% and 22% respectively.

My take: When we find effective therapies, we will need better non-invasive markers to follow NAFLD progression.
