Comparison of blood flow signals in patients in the nodular hepatocellular carcinoma group and FNH group (n (%)).

Group	n	Grade 0	Grade 1	Grade 2	Grade 3
Nodular hepatocellular carcinoma	102	0 (0.00)^c	13 (12.75)^c	53 (51.96)^c	36 (35.29)^c
FNH	50	30 (60.00)	18 (36.00)	2 (4.00)	0 (0.00)
X^2		76.249	11.176	33.423	23.124
		≤0.001	≤0.001	≤0.001	≤0.001

Compared with the FNH group, ^c < 0.01.
