Detection of hepatic steatosis with ultrasound-guided attenuation parameter (UGAP) in metabolic dysfunction-associated steatotic liver disease (MASLD) compared with proton density fat fraction (PDFF): Impact of measurement number and region of intere

Ultrasound-guided attenuation parameter diagnostic performance to detect hepatic steatosis ⩾ S1 in metabolic dysfunction-associated steatotic liver disease is similar with regions of interest in single versus multiple lateral locations. Three measurements in multiple lateral locations appear sufficient to detect hepatic steatosis, which must be evaluated for all hepatic steatosis stages.
