1. Dual-Energy CT in Children: Imaging Algorithms and Clinical Applications
With dual-energy CT, clinical images are obtained at high- and low-energy spectra, allowing differences in material composition to be depicted.
Dual-energy CT images are helpful in assessment of the arterial system, lung perfusion, neoplasm, bowel diseases, renal calculi, tumor response to treatment, and metal implants.
Dual-energy CT can be performed with radiation exposure level that is equivalent to or less than that of conventional single-energy CT.
