Multicenter study for diagnosing hepatic steatosis using attenuation measurement (ATT); Comparison with PDFF (MRI-determined proton density fat fraction). - ATT (Attenuation Measurement) study

Bland-Altman analysis showed minimal fixed bias between iATT and MRI-PDFF with excellent reproducibility. The area under the curve to distinguish lipodystrophy grades 1, 2, and 3 was 0.887, 0.882, and 0.867, respectively. Skin to capsular distance greater than 25 mm was identified as the only significant factor causing discordance. no interaction between MRI-logPDFF and MRE-LSM on iATT values was observed.
