Attenuation imaging is an emerging method (c.2022) used for detection hepatic steatosis. It provides the function of quantifying and reducing the colour code of liver decay factors, which may be due to changes in hepatic composition (such as increased fat content) 1-3.
The ATI value is defined as db/cm/MHz × 100. The values increase with increasing levels of steatosis.
