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.

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 ...

Interest in dual-energy CT (DECT) for evaluating the myocardial blood supply, as an addition to coronary artery assessment, is increasing. Although it is still in the early clinical phase, assessment of myocardial ischemia and infarction by DECT constitutes a promising step toward comprehensive evaluation of coronary artery disease with a single ...

Thoracic Applications of Dual Energy
Radiologic Clinics of North America, 2010Recent technological advances in multidetector computed tomography (CT) have led to the introduction of dual-source CT, which allows acquisition of CT data at the same energy or at 2 distinct tube voltage settings during a single acquisition. The advantage of the former is improvement of temporal resolution, whereas the latter offers new options for CT

A system for dual-energy radiography
The British Journal of Radiology, 1983A system has been developed and theoretically analysed for the generation of chemical information from conventional radiography. A specially modified cassette has enabled dual-energy radiographs to be taken during a single exposure. A simple theoretical model has demonstrated that the concept of an optical density "standardised" to the local ...

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.
