Figure 13  Axial short tau inversion recovery and diffusion-weighted imaging. A and B: Axial short tau inversion recovery (A) and diffusion-weighted imaging (DWI) (B) images showed a < 10 mm segment VII observation with high signal intensity; C and D: In the arterial phase (C), arterial phase hyperenhancement was seen with washout in the portal phase (D) categorized as LR-4. Restriction on DWI does not allow to upgrade from LR-4 to LR-5, because ancillary features lack sufficient specificity for hepatocellular carcinoma to allow for an LR-5 upgrade.
