Dual-energy CT (DECT) scan mode was introduced in 2006. It uses two different X-ray energy spectra simultaneously to obtain additional information on tissue composition [1]. The basic principle of DECT is the acquisition of two datasets with different energy spectra, from the same anatomic location [2].

, 2008 In recent years, developments in CT, especially the development of multi-detector CT (MDCT), have provided new and better tools for the evaluation of patients presenting with hematuria and flank pain. The ability of MDCT to provide rapid contiguous thin-slice imaging through the abdomen allowed for the development of CT urography (CTU) protocols for ...

Dual-Energy Imaging of the Chest
Seminars in Ultrasound, CT and MRI, 2022Dual-energy computed tomography (DECT) is a contemporary development by which the tissue can be characterized beyond conventional computed tomography. It improves tissue differentiation by exploiting the X-ray absorptive property of the tissues. Although still in its early stages, DECT utilization in pulmonary and cardiovascular pathologies is emerging.

Optimum energies for dual-energy computed tomography
Physics in Medicine & Biology, 1980By performing a dual-energy scan, separate information can be obtained on the Compton and photoelectric components of attenuation for an unknown material. This procedure has been analysed for the optimum energies, and for the optimum dose distribution between the two scans.

An energy sensitive cassette for dual‐energy mammography [PDF]
Medical Physics, 1989 A cassette for simultaneously acquiring dual‐energy mammographic images is proposed and studied utilizing a theoretical noise analysis model. The cassette consists of a sandwich of two storage phosphor plates separated by a copper filter. The front, low atomic number, plate was assumed to be comprised of SrFBr and the rear, high atomic number, plate of

Thoracic Applications of Dual Energy
Seminars in Respiratory and Critical Care Medicine, 2014Computed tomography (CT) is the core imaging modality for the evaluation of thoracic disorders. With the recently developed dual-energy CT (DECT) technique, the clinical utility of CT in the management of pulmonary diseases can be expanded. The most actively investigated principle of dual energy is material decomposition based on attenuation ...

Gout is caused by genetic disposition and alimentary factors. It comprises a heterogeneous group of disorders characterized by deposition of monosodium urate crystals in the joints and tendons. Asymptomatic hyperuricemia is common and should not ordinarily be treated. Gout progresses through four clinical phases: asymptomatic hyperuricemia, acute gouty

The introduction of dual-energy CT (DECT) has ushered in the ability of material differentiation and tissue characterization beyond the traditional CT attenuation scale. This quality has been exploited for visualizing and quantifying the specific tissue content using radiographic contrast agents, such as iodine-based contrast media or inhaled xenon gas.
