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

Table 5

The differences of liver surface parameter at 20 minutes post-Gd-EOB-DTPA injection among different categories of fibrosis.

MRI liver		biopsy n (%)
surface irregularity grade		F0	F1-F2	F3-F4	Comparison	Chi-squared (Pearson), sig. (p),
Liver surface	1	14(73,7)	10(31,3)	0(0.0)	F0 vs. F1+F2	8,62
20 min.	2	5 (26,3)	22(68,8)	3(11,1)	F0 vs. F3+F4	38,27
	3	0(0,0)	0(0,0)	24(88,9)	F1+F2 vs. F3+F4	48,36

Differences between F0, F1-F2, and F3-F4 biopsy groups were analyzed by Pearson's chi-square test; p<0,001, p<0,01, p<0,05, NS: nonsignificant.
