Noninvasive Assessment of Liver Fibrosis in Patients with Chronic Hepatitis B or C by Contrast-Enhanced Magnetic Resonance Imaging

Table 3

The liver signal intensity Q-LSCR parameter differences at 20 minutes post-Gd-EOB-DTPA injection among different categories of fibrosis.

	Biopsy	N	min.-max.	mean (STD)	Group comparison; sig., F (ANOVA)	Post hoc Sheffe,; sig. (P)
Q-LSCR	F0	19	1,31-3,01	2,19(0,39)	15,38	F0<F1+F2
20 min.	F1-F2	32	0,99-2,98	2,24(0,39)		F0>F3+F4
	F3-F4	27	1,27-2,71	1,77(0,33)		F1+F2>F3+F4

Q-LSCR = quantitative liver-spleen contrast ratio; differences between F0, F1-F2, and F3-F4 biopsy groups were analyzed by ANOVA; Scheffe's method of post-hoc test was used to compare differences between the tree groups (F0 versus F1-F2, F0 versus F3-F4, and F1-F2 versus F3-F4); p<0,001, p<0,01, p<0,05, NS: nonsignificant.
