Abstract

Attenuation imaging (ATI) is a method to quantitatively assess steatosis by using fat attenuation technique that is installed on Aplio i800, an all-purpose ultrasound diagnostic device (Toshiba Medical Systems). We assessed the correlation between Controlled Attenuation Parameter (CAP) and ATI in 116 patients with chronic hepatitis. Two methods showed excellent correlation (Pearson's r=0.699, 95% CI 0.592-0.782). ATI can be used as a method to assess steatosis without a device dedicated to ATI method.
