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 interest (ROI) location.

ABSTRACT:

Background

The ultrasound-guided attenuation parameter is well established for hepatic steatosis detection in metabolic dysfunction-associated steatotic liver disease. The diagnostic performance of ultrasound-guided attenuation parameter was evaluated using different numbers of measurements at different lateral locations to detect hepatic steatosis ⩾ S1 in male and female patients with metabolic dysfunction-associated steatotic liver disease.

Methods

A metabolic dysfunction-associated steatotic liver disease cohort was prospectively enrolled in autumn of 2022. Ultrasound-guided attenuation parameter values obtained through one to five measurements, performed at single and multiple locations, were compared with proton density fat fraction. Presence of hepatic steatosis (i.e.
