Table 3

Comparison of color Doppler ultrasound blood flow parameters between the nodular hepatocellular carcinoma group and FNH group (‾x ± s).

Group	n	Hepatic artery diameter (mm)	Peak hepatic artery velocity (cm/s)	Minimum flow velocity of hepatic artery (cm/s)	Resistance index (RI)	Portal vein flow rate (cm/s)
Nodular hepatocellular carcinoma	102	5.56 ± 0.42^b	118.32 ± 15.73^b	22.65 ± 3.12^b	0.84 ± 0.06^b	10.52 ± 1.08^b
FNH	50	4.02 ± 0.31	63.25 ± 5.97	8.69 ± 1.62	0.44 ± 0.03	18.01 ± 3.69
t		3.310	7.963	3.569	5.301	-3.126
P		0.015	≤0.001	0.012	0.001	0.029

Compared with the FNH group, ^b < 0.05.
