Table 4 Sensitivity, specificity and A_z value for differential diagnosis based on CE 3D US in prospective study

Focal liver tumors	Diagnostic criteria based on combined enhancement patterns		Sensitivity	Specificity	A_z value
HCC	1, 2, 4, 6, 17, 18, 20	Reader 1	91 (64/70)	90 (44/49)	0.94 (0.88-0.95)
		Reader 2	94 (66/70)	92 (45/49)	0.96 (0.91-0.98)
Metastasis	3, 7, 8, 9, 13, 19, 21, 22, 23	Reader 1	86 (24/28)	97 (88/91)	0.95 (0.89-0.98)
		Reader 2	82 (23/28)	96 (87/91)	0.94 (0.89-0.97)
Hemangioma	10, 11, 12, 14, 15, 16, 24	Reader 1	94 (15/16)	98 (101/103)	0.98 (0.94-1.00)

FNH	5	Reader 1	80 (4/5)	98 (112/114)	0.99 (0.95-1.00)
		Reader 2	80 (4/5)	99 (113/114)	0.98 (0.87-1.00)

Combined enhancement patterns for diagnostic criteria are summarized according to the serial numbers in Table 3. Sensitivity and specificity data are presented as percentages with numbers of tumors in parentheses, and A_z values are presented with 95% confidence intervals in parentheses.
