In the field of cardiovascular medicine, dual-energy CT has been applied to the evaluation of myocardial ischemia [], myocardial viability [], and atherosclerotic plaque characterization [] as outlined in the previous chapters. Dual‐Energy CT (DECT) The fundamental principle behind the use of DECT is to differentiate materials based on their relative absorption of X‐rays at different photon energy levels (typically at 80 and 140 kVp). Ideally, the materials to be differentiated should be simultaneously imaged at the two different energy levels. •Dual Energy CT (DECT) technology is available on scanners from several vendors and offers significant advantages over classic single energy CT technology in multiple clinical applications.

Computed tomography is the main source for patient radiation doses Working with dual-energy CT protocols-tips for optimization (PN). 14.30-
MRI clearly demonstrates bone marrow oedema lesions (BMEL) as a sign of inflammation.3 Dual-energy CT (DECT) scanners could provide a new approach to visualise BME.4–7 We investigated if DECT CT imaging. New Approaches for Dual Energy CT Using Dual Source CT Systems Dual source CT is a CT system where two x-ray sources and two data acquisition systems are mounted on the same x-ray gantry, positioned orthogonally to one another on the gantry.4-6 A commercial dual source CT system was introduced in 2006 (SOMATOM Definition, Dual-energy CT is a novel, rapidly emerging imaging technique which offers important new functional and specific information. In this book, physicists and specialists from different CT manufacturers provide an insight into the technological basis of, and the different approaches to, dual-energy CT.

OBJECTIVE In dual-energy CT (DECT), two CT datasets are acquired with different x-ray spectra. These spectra are generated using different tube potentials, Dual-energy imaging is a promising new development in computed tomography ( CT) that has the potential to improve lesion detection and characterization 31 May 2019 From April 2019 onwards, they are implementing a novel, patient-specific method of proton range prediction based on dual-energy CT (DECT). En relativt ny funktion hos moderna datortomografer är ”dual energy” vilket innebär att bilder framställs med två olika energinivåer. Detta kan uppnås på olika Dual energy CT. Projekt: Forskning.
