Table 6. The diagnostic value of CEUS indicators in the pathological grading of HCC.

Variables	AUC	P	Sensitivity	Specificity	Accuracy
RT	0.802	<0.001*	100	50.48	0.5048
TTP	0.773	<0.001*	78.26	86.67	0.6493
Enhancement rate	0.775	<0.001*	73.91	88.57	0.6248

*, P<0.05. CEUS, contrast-enhanced ultrasound; HCC, hepatocellular carcinoma; AUC, area under the curve; RT, rise time; TTP, time to peak.
