Gene expression and MR diffusion-weighted imaging after chemoembolization in rabbit liver VX-2 tumor model

Table 3 ADC values of the tumor and normal parenchyma (mean ± SD, × 10^-3 mm²/s)

	ADC in tumor periphery area		ADC in normal parenchyma
	b = 100	b = 300	b = 100	b = 300
A time	1.71 ± 0.27	1.48 ± 0.23	2.71 ± 0.42	2.30 ± 0.40
B time	1.24 ± 0.22	1.12 ± 0.20	2.10 ± 0.54	1.65 ± 0.37
C time	1.48 ± 0.37	1.23 ± 0.16	2.10 ± 0.49	1.97 ± 0.29
D time	1.57 ± 0.23	1.40 ± 0.18	2.43 ± 0.33	2.06 ± 0.23

A time is before chemoembolization or on the 21th day after implantation. B time, C time, and D time represent samples obtained after 16 h, 32 h and 48 h after chemoembolization respectively.
