In a DECT scan, projections are acquired at 140 kV (orange solid line) and 80 kV (green dashed like) alternatively at every 0.2 milliseconds. This review article aims to summarize the available literature regarding the utility of Dual-Energy CT (DECT) in spine imaging. DECT using virtual non-calcium images, virtual monoenergetic images, and material decomposition techniques have shown promise in bone marrow edema visualization associated with vertebral fractures, metallic artifact reduction related to spinal hardware, axial Dual Energy CT 今回は、近年注目されているDual Energy CT（以下DECT）についてお話させて頂きます。 説明するにあたり、まず従来使用しているCTであるSingle Energy CTの課題について述べ、続いてDual Energy撮影法、そして臨床応用という流れでまとめてみました。 2021-04-13 · Active joint inflammation is a key feature in rheumatoid arthritis (RA). Treatment guidelines for RA,1 including ‘Treat-to-Target’ strategies,2 stress the importance of abrogation of inflammation. 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.

Vi erbjuder bland annat kompressorer, vakuumpumpar, generatorer, pumpar,  Dual energy CT, also known as spectral CT, is a computed tomography technique that uses two separate x-ray photon energy spectra, allowing the interrogation of materials that have different attenuation properties at different energies. In dual-energy CT (DECT), two CT datasets are acquired with different x-ray spectra. These spectra are generated using different tube potentials, partially also with additional filtration at 140 kVp. Spectral information can also be resolved by layer detectors or quantum-counting detectors. Dual-energy CT or multispectral CT is becoming increasingly more common in clinical practice due to the rapid rise in computer technology and expanding literature exhibiting vast advantages over conventional single energy CT. Dual-energy CT is a tremendous innovation in CT technology that allows creation of acquisitions at more than one energy spectrum and provides improved lesion detection and characterization, superior determination of material composition, reduction in dose of iodine, and more robust quantification. During a Dual Source Dual Energy scan, two CT datasets are acquired simultaneously with different kV and mA levels, allowing you to visualize differences in the energy-dependence of the attenuation coefficients of different materials. These images are combined and analyzed to visualize information about anatomical and pathological structures.

imaging at two energy levels, is a special case of spectral imaging and is still the most widely used terminology, but the terms "spectral imaging" and "spectral CT" have been coined to acknowledge the fact that photon-counting detectors have the potential for measurements at a larger number of energy levels. Dual energy CT was first proposed by Godfrey Hounsfield in 1973 [1]. Subsequent investigations led to the development of a commercial CT system with dual energy capabilities [2-4].

•This technology utilizes photon spectra generated by two different tube voltages to identify and distinguish different materials in the body such as Dual Energy CT: Basic Principles (1.1) Here μ is the linear attenuation coefficient of the x-rays at point ( x , y , z ), L is the thickness of the tissue crossed by the x-ray beam, and s is the coordinate along the path of the x-ray beam. With the new version of the Somatom Definition Edge, Siemens Healthcare has created the basis for establishing the dual energy procedure in clinical routine. The innovative X-ray tube concept in the new CT scanner, enables simultaneous imaging at two different energy levels for the first time in single source computed tomography., With the new version of the Somatom Definition Edge, Siemens Dual-energy CT provides information about how substances behave at different energies, the ability to generate virtual unenhanced datasets, and improved detection of iodine-containing substances on low-energy images.
