PV: portal vein, PV flow (ml/s), PV velocity (cm/s), D (true diffusion coefficient, ×10⁻³ mm²/s), D* (pseudodiffusion coefficient, ×10⁻³ mm²/s), PF (perfusion fraction, %), ADC (apparent diffusion coefficient, ×10⁻³ mm²/s), liver stiffness (liver stiffness, kPa).

**First fasting measurement.

***Paired Wilcoxon test.

****Calculated as 100*(postprandial-fasting)/fasting.

****LS calculated in 27 subjects.
