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

Table 4

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

		Biopsy n (%)
MRI homogeneity grade		F0	F1-F2	F3-F4	Comparison	Chi-squared (Pearson), sig. (P),
Homogeneity	1	9(47,4)	4(12,5)	0(0,0)	F0 vs. F1+F2	8,59
20 min.	2	10(52,6)	25(78,1)	7(25,9)	F0 vs. F3+F4	29,02
	3	0(0,0)	3(9,4)	20(74,1)	F1+F2 vs. F3+F4	26,45

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.
