Updates on Quantitative MRI of Diffuse Liver Disease: A Narrative Review

Figure 1

Fat fraction MRI images of a 65-year old male patient with NAFLD. (a) MRI-PDFF: 3D Ax IDEAL-IQ image. (b) MRI-PDFF: 3D Ax IDEAL-IQ image with ROIs placed showing high values of fat deposition than normal liver (>5%). (c) R2 3D Ax IDEAL-IQ image representing the T2 correction needed to estimate MRI-PDFF. (d) Water 3D Ax IDEAL-IQ image as expression of different echo times used for the IDEAL-IQ sequence acquisition. MRI-PDFF: magnetic resonance-fat fraction of the estimated proton density; echo asymmetry and least squares estimation (IDEAL-IQ); NAFLD: nonalcoholic fatty liver disease; ROIs: regions of interest.
