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

Table 3 Classification of lesions based on iodine concentration (μg/mL)

Iodine concentration (μg/mL)	0-15 (low)	16-30 (moderate)	31-45 (high)	≥ 46 (extreme)
Ameloblastoma	2	11	4	1
CGCG	0	1	8	0
OKC	5	0	0	0
OF	0	3	0	0
Salivary gland tumor	1	1	0	0
Chondromyxoid fibroma	0	0	0	1
Others	4	6	2	1

All odontogenic keratocysts had a lower iodine concentration (0-15). Ameloblastomas predominantly had a moderate iodine concentration (16-30). Central giant cell granuloma predominantly had a higher iodine concentration (31-45). OKC: Odontogenic keratocysts; OF: Ossifying fibromas; CGCG: Central giant cell granuloma.
