Liver fibrosis is an important public health problem, with a substantial morbidity and mortality due to progression to cirrhosis and hepatocellular carcinoma. All causes of chronic liver disease may lead to fibrosis. The traditional diagnostic approach requires a biopsy for assessing the severity of liver disease prior to therapy. However, liver biopsy has several limitations: cost, sampling error, and procedure-related morbidity and mortality. Considering the high prevalence of viral hepatitis and nonalcoholic fatty liver disease, a condition often associated with obesity and type 2 diabetes, there is an urgent need for noninvasive screening, diagnosis and monitoring strategies of chronic liver disease severity. Our team has the expertise to investigate ultrasound-based and magnetic resonance-based elastographic methods for the noninvasive staging of liver fibrosis. The primary objective of this cross-sectional study is to compare the sensitivity of elastographic methods for detecting histology-determined significant fibrosis. The secondary objectives are to compare the diagnostic accuracy of these elastographic methods and the influence of potential confounders (inflammation, steatosis and iron deposition) on their diagnostic accuracy.
