ObjectivesThe dual-energy computed tomographic (DECT) technique allows the differentiation of materials with large atomic numbers such as iodine. The basic principle of dual-energy CT is material decomposition based on attenuation differences at different energy levels. The parameters for iodine extraction are a minimum value of – 960 HU, and a maximum of –600 HU. Lung parenchyma with normal perfusion in this attenuation range is presented in orange, and an area of decreased perfusion is visualized as an iodine defect area.
