Fig. 2.

cT1 values in 77 patients and 7 healthy volunteers (presumed with no fibrosis) plotted against their biopsy proven fibrosis stage. Iron-corrected T1 (cT1) correlates with the degree of fibrosis in all subjects (r_s = 0.68, p <0.0001, 95% CI 0.54–0.78). Mean ± SD cT1 for each group was as follows: healthy volunteers 717 ± 48 ms, no fibrosis 750 ± 42 ms (those two are grouped as “normal liver”), mild fibrosis 870 ± 104 ms, moderate 873 ± 63 ms, and severe 1025 ± 102 ms. ANOVA with Bonferroni’s correction showed significant differences (^⁎⁎⁎) between all groups apart from mild vs. moderate fibrosis (n.s., not significant; Table 2). Liver biopsy patients are shown as red dots, and healthy volunteers as blue squares.
