Table 9

Value of 2D gray scale + CDFI and 2D-CEUS in diagnosing AT-OCLH.

Method	N; (Case)	TP	FP	TN	FN	Sen; (%)	Spe; (%)	LR^+	LR^-	PV^+; (%)	PV^-; (%)	Consist ency; (%)
2D-CEUS	52	22	1	28	1	95.7	96.6	27.74	0.05	95.7	96.6	96.2
2D ray-scale; + CDFI	52	10	14	15	13	43.5	51.7	0.90	1.09	41.6	53.5	48.1

Note. TP: true positive; FP: false positive; TN: true negative; FN: false negative; Sen: sensitivity; Spe: specificity; LR+: positive likelihood ratio; LR-: negative likelihood ratio; PV+: positive predictive value; PV-: negative predictive value.
