Non-invasive diagnosis and staging of non-alcoholic fatty liver disease
Open accessAbstract
Non-alcoholic fatty liver disease (NAFLD) is considered to be the hepatic manifestation of the metabolic syndrome and is characterized by ectopic accumulation of triglycerides in the cytoplasm of hepatocytes, i.e., steatosis. NAFLD has become the most common chronic liver disease, with an estimated global prevalence of 25%. Although the majority of NAFLD patients will never experience liver-related complications, the progressive potential of NAFLD is indisputable, with 5–10% of subjects progressing to cirrhosis, end-stage liver disease, or hepatocellular carcinoma. NAFLD patients with advanced fibrosis are at the highest risk of developing cardiovascular and cirrhosis-related complications. Liver biopsy has hitherto been considered the reference method for evaluation of hepatic steatosis and fibrosis stage. Given the limitations of biopsy for widescale screening, non-invasive tests (NITs) for assessment of steatosis and fibrosis stage, including serum-based algorithms and ultrasound- and magnetic resonance-based methods, will play an increasing role in the management of NAFLD patients. This comprehensive review presents the advantages and limitations of NITs for identification of steatosis and advanced fibrosis in NAFLD. The clinical implications of using NITs to identify and manage NAFLD patients are also discussed.

Imaging techniques are not ideal for mass screening due to significant drawbacks including high cost, lack of safety, lack of consensus, limited accessibility, and complexity.
“However, these methods are usually used for disease diagnosis and are not ideal for mass screening due to significant drawbacks, including high cost (CT and MRI scans), lack of safety (CT scans), lack of consensus (biomarker-based indices), limited accessibility (transient elastography, MRI scans), and complexity (MRI scans) [41, 42].”

The Steatosis sections on computed tomography and magnetic resonance techniques (pages not provided) support CT radiation exposure and MRI’s cost, limited availability, and time demands. The serum-biomarker section says no algorithm can yet be recommended as an initial NAFLD screening tool. The copy does not identify high CT cost as a drawback, and the Clinical implications section calls VCTE the most widely available liver-stiffness measurement device, rather than describing it as having limited accessibility.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
