A novel dual energy CT-based attenuation correction method in PET/CT systems: A phantom study

  In present PET/CT scanners, PET attenuation correction is performed by relying on the information given by CT scan. In the CT-based attenuation correction methods, dual-energy technique (DECT) is the most accurate approach, which has been limited due to the increasing patient dose. In this feasibility study, we have introduced a new method that can implement dual-en...

Dual-Energy CT in Neuroimaging

Image contrast in CT is mostly dependent on elements with high atomic weight, such as calcium, iron, and iodine The concentrations of these elements can be calculated from dual-energy x-ray data based on their characteristic attenuation patterns Dual-energy CT may can be helpful in neuroimaging to: Differentiate between hemorrhage and iodinated contrast agents in brain parenchyma Improve CT ang...
