Quantitative ultrasound measurement of the liver fat. Tissue attenuation imaging (A) and tissue scatter distribution imaging (B) of participants with a liver fat content of <5%. For visual reference, colormaps from magnitude-based estimation of MRI-PDFF values were also reconstructed on axial slices where livers with < 5% MRI-PDFF showed blue color indicating no significant steatosis (C). Patients with 5–10% of MRI-PDFF had higher TAI (D) and TSI (E) values compared to patients with no significant hepatic steatosis, while the MRI-PDFF colormap of the liver turned green (F). Finally, patients with ≥ 10% of MRI-PDFF had the highest TAI (G) and TSI values (G), and they had a yellowish color on the MRI-PDFF colormap (I). MRI-PDFF = magnetic resonance imaging-based proton density fat fraction measurement, TAI = tissue attenuation imaging, TSI = tissue scatter distribution imaging.
