66-year-old male patient with HCV and Metavir stage 1 fibrosis. Parametric IVIM diffusion maps of the abdomen at 1.5 T (Coronal, A–D) and 3.0T (axial, E–H). A, E: SS EPI diffusion image (b200). (B and F): D map (true diffusion coefficient, mm2/s). (C and G): PF map (perfusion fraction, %). (D and H): D* map (pseudodiffusion coefficient mm2/s). D maps show slightly higher values at the 1.5 T than the 3.0 T. D* maps show higher values at the 1.5 T compared to the 3.0 T. PF maps show lower values at the 1.5 T compared to the 3.0 T. Calculated values were as follows: for D, 0.97 and 0.94 × 10−3 mm2/s at the 1.5 T and the 3.0 T, respectively; for PF, 18.9% and 27.7%, respectively; for D*, 82.9 and 60.3 × 10−3 mm2/s, respectively.
