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

Figure 4 Multilocular solid-cystic lesions differentiated based on iodine concentration. A-C: Central giant cell granuloma - A well-defined expansile multiloculated solid-cystic tumor in the left anterior mandible crossing the midline. Iodine images with a color overlay (C) showed an iodine concentration (IC) of 57 × 100 μg/cm³ of the solid enhancing part (orange arrow); D-F: Ameloblastoma - a well-defined lytic, unilocular, solid-cystic, expansile lesion with an enhancing soft tissue component (orange arrow). Iodine images with a color overlay (F) show increased iodine content (areas in red) within the soft tissue (IC of 23 × 100 μg/cm³).
