Diagnostic Value of MRI Proton Density Fat Fraction for Assessing Liver Steatosis in Chronic Viral C Hepatitis

Table 2

Distribution of MRI PDFF values according to different METAVIR stages of hepatic fibrosis. The Kruskal-Wallis test revealed a significant difference between groups (). The post-hoc analysis demonstrates that the median MRI PDFF value of the F4 subgroup is significantly lower than that of the other subgroups of patients.

Post-hoc analysis: distribution of PDFF according to METAVIR stages of fibrosis
Factor		Median (range)	Average rank	Pairwise comparisons with a significant result ()
F0	23	6.7 (0.72–17.01)	44.61	F0 versus F4
F1	14	6.7 (0.7–15.54)	43.25	F1 versus F4
F2	12	6.07 (3.68–15.04)	40.33	F2 versus F4
F3	18	5.78 (3.7–15.54)	39.36	F3 versus F4
F4	10	3.43 (1.72–5.95)	17.90	F4 versus F0/F1/F2/F3
