Contrast-Enhanced Ultrasound to Monitor Early Recurrence of Primary Hepatocellular Carcinoma after Curative Treatment

Table 3

Comparison of CEUS and CECT/MRI in the detection of arterial vascularization in recurrent HCC based on high enhancement in the arterial phase.

	Recurrent HCC		Sensitivity	Specificity	PPV	NPV
	Yes (n=99)	No (n=25)
Enhancement; by CEUS
Yes	96	8	97.0%; (96/99)	68.0%; (17/25)	92.3%; (96/104)	85.0%; (17/20)
No	3	17
Enhancement; by CECT/MRI
Yes	71	9	71.7%; (71/99)	72.0%; (18/25)	88.8%; (71/80)	39.1%; (18/46)
No	28	18
P	<0.001

PPV, positive predictive value; NPV, negative predictive value.
