Dual-energy computed tomography in children: Technique and clinical applications

Figure 14  An 11-month-old male with hepatoblastoma. A: Blended contrast-enhanced axial image showed a large isodense mass in the liver with poor demarcation of the mass with the adjacent liver due to minimal enhancement; B: Virtual non-contrast image showed no evidence of calcification/fat/hemorrhage within the lesion; C and D: Iodine overlay images showed iodine uptake in the periphery of the mass with attenuation on the virtual non-contrast image being 475 Hounsfield units and on the blended image being 903 Hounsfield units, suggesting significant enhancement that was not well appreciated on the blended image; E: Iodine-specific image showed the iodine content in the periphery of the mass to a better advantage.
