  		Figure 1a. Scatterplots depict substantial correlations (a) between portal fraction of liver perfusion and portal pressure (r = -0.769, P < .001) and (b) between mean transit time and portal pressure (r = 0.721, P < .001). Portal fraction of liver perfusion and mean transit time are calculated with the dual-input one-compartmental model from the MR imaging data.

  		Figure 2b. Scatterplots depict the weak but significant correlations (a) between portal blood flow and portal pressure (r = 0.317, P = .043) and (b) between right hepatic artery resistance index and portal pressure (r = 0.419, P = .007). Portal blood flow and hepatic artery resistance index are calculated with Doppler US.
