Abstract

Purpose of Review

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in the Western world. Invasive liver biopsy remains the gold standard method for the diagnosis and staging of NAFLD. The aim of this review is to summarize recent research regarding imaging-based assessment of NAFLD.

Recent Findings

Novel methods such as controlled attenuation parameter (CAP) and magnetic resonance imaging proton-derived fat fraction (MRI-PDFF) appear promising for steatosis assessment and are currently undergoing validation in NAFLD. Fibrosis can be non-invasively assessed by transient elastography (TE), which is currently the best validated test in NAFLD. MR elastography (MRE) appears very sensitive for fibrosis detection. No imaging technique can accurately detect NASH.

Summary

TE is inexpensive and relatively widely available and can reliably exclude advanced fibrosis in NAFLD. MRI offers the most promise for steatosis and fibrosis quantification, but further validation of these techniques is needed.

Keynote webinar | Spotlight on medication adherence

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
