Characterization of tumors of jaw: Additive value of contrast enhancement and dual-energy computed tomography

Table 5 Receiver operating characteristic analysis of dual-energy computed tomography parameters between ameloblastoma and central giant cell granulomas

Variable	Cutoff value	Sensitivity, %	Specificity, %	AUC	SE
IC	32.1	81.82	65.00	0.727	0.0955
Mean HU	134	81.82	65.00	0.789	0.0832
WC	1036	72.73	50.00	0.6659	0.1
NIC	0.4	81.82	70.00	0.795	0.0970

Mean HU is the mean computed tomography density expressed in Hounsfield units. IC: Iodine concentration; WC: Water concentration; NIC: Normalized iodine concentration; AUC: The area under the receiver operating characteristic curve.
