Fig. 1A. 68-year-old man with cirrhosis. Transverse dynamic CT scans
obtained during portal phase using contrast medium concentrations of 300 mg
I/mL (A) and 370 mg I/mL (B) show that intrahepatic portal
branches (arrows) are visualized better in B than in
A.

Fig. 2A. 64-year-old man with cirrhosis. Transverse dynamic CT scans
obtained during late phase using contrast medium concentrations of 300 mg I/mL
(A) and 370 mg I/mL (B) show that hepatic parenchyma enhancement
(arrows) is greater in B than in A. Contrast
enhancement values are 37 H and 27 H, respectively.
