Research advances in radiological examination for nonalcoholic fatty liver disease / 临床肝胆病杂志

ABSTRACT

There is a high prevalence of nonalcoholic fatty liver disease (NAFLD) around the world, and early diagnosis and evaluation of liver fatty degeneration and fibrosis degree play important roles in the early treatment and prognostic evaluation of patients with NAFLD. This article reviews the principles, diagnostic accuracy, influencing factors, and practicability of various imaging techniques applied in liver fat quantification and fibrosis prediction. Studies have shown that radiological fat quantitative diagnosis based on ultrasound and magnetic resonance and liver fibrosis evaluation based on elastography have a high level of accuracy and promising prospects; however, such techniques lack standard cut-off values and operating procedures which may provide a reference for clinical application.
