Figure 4

SNR and CNR versus liver tissue for (A) the aorta, (B) the portal vein, and (C) the hepatic vein. SNR is displayed by solid lines, CNR by dashed lines with data points. Thin dashed lines represent average ± 95% confidence interval over all subjects. Gadobenate dimeglumine images demonstrated slightly higher SNR. CNR of vessels vs. liver, however, was greater using gadoxetic acid in the delayed phase. Significance levels are indicated (dashed black line, asterisk) where differences showed statistically significance to the p<0.05 level. The blue shaded area represents the dynamic phase. Due to study design, measurements at 5 and 30 minutes were not acquired.
