Using IVIM-MRI and R2⁎ Mapping to Differentiate Early Stage Liver Fibrosis in a Rat Model of Radiation-Induced Liver Fibrosis

Table 1

Relative T1 and T2 values of left and right lobes at different time points.

	base	1m	2m	3m	χ^2 (P)
T1 of right lobes					5.72 (0.13)
T1 of left lobes					6.94 (0.07)
Z value (P)	0.97 (0.33)	1.60 (0.11)	1.07 (0.29)	1.10 (0.27)	—
T2 of right lobes					4.27 (0.23)
T2 of left lobes					4.30 (0.27)
Z value (P)	0.36 (0.72)	0.54 (0.59)	1.07 (0.29)	0.73 (0.47)	—

note: base, 1m, 2m, and 3m denote the groups before and one, two, and three months after radiation.
