Intergroup comparisons (P value 1) and intragroup comparisons (P value 2, comparison to baseline values) were made using mean values for each variable, and P < 0.05 indicates statistically significant differences between groups. P values refer to unpaired t tests with unequal variance. Reference SUV_max of normal hepatic parenchyma are also included.
