Background: Dual-energy computed tomography (DECT) has been shown to be useful for subtracting bone or calcium in CT angiography and gives an
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.
Mål Att utvärdera dual-energy spektral CT-avbildning vid utvärdering av graden av differentiering i tjocktarmscancer.
Diagnostic imaging has been a widely used tool in the Overall, it seems that dual-energy scans can be completed with doses similar or slightly higher than traditional, single-energy CT. Spectral CT. An even newer technology just becoming available is so-called spectral CT, which relies on a totally different mechanism to differentiate materials by x-ray energy absorption. Principle of Dual Energy CT – Image Based Evaluation Each material is characterized by its „Dual Energy Index “ x80 and x 140 are the Hounsfield numbers at 80 kV and 140 kV, resp . Dual energy CT can measure chemical composition !
Dual-energy CT has remained underutilized over the past decade probably due to a cumbersome workflow issue and current technical limitations.

Dual-energy CT (DECT) is not new, in fact, says Benjamin Yeh, MD, it has been around just as long as computed tomography (CT) has.
