Clinical Utility of Ultrasound-Guided Attenuation Parameter for the Detection and Quantification of Hepatic Steatosis in Patients with Fatty Liver Diagnosed by Computed Tomography.

This retrospective study was aimed (i) at elucidating the correlation between fatty liver diagnoses based on the plain computed tomography (CT) value and those based on the attenuation coefficient (AC) value determined with the ultrasound-guided attenuation parameter (UGAP) and (ii) at evaluating the diagnostic power of AC values. We included 125 patients who underwent blood tests, abdominal ultrasonography and abdominal CT at our department between April 2020 and March 2021. Hepatic fat infiltration was categorized as S0 (<5%), S1 (≥5 and 30<%), S2 (≥30 and <50%) or S3 (≥50%).
