Summary
The review discusses the current state of attenuation imaging for fat quantification, focusing on the American Institute of Ultrasound in Medicine–RSNA Quantitative Imaging Biomarkers Alliance Pulse-Echo Quantitative Ultrasound Initiative.
Nonalcoholic fatty liver disease (NAFLD) is a prevalent chronic liver disease, and accurate assessment of liver fat content is crucial for identifying and monitoring patients with or at risk for NAFLD. The initiative explores three quantitative ultrasound parameters: attenuation, backscatter coefficient, and speed of sound.
The review provides insights into the examination performance and interpretation of attenuation imaging for fat quantification and identifies areas that require further study.
