A dual-source CT scan uses two x-ray sources at right angles to each other. This doubles the speed of the test so you receive less radiation, and it also creates 

2016-09-21 Dual-energy CT (DECT) is a tremendous innovation in CT technology that allows creation of numerous imaging datasets by enabling discrete acquisitions at more than one energy level. The wide range of images generated from a single DECT acquisition provides several benefits such as improved lesion detection and characterization, superior Using three material differentiation, dual-energy CT scans can be post-processed to remove bone which is particularly advantageous in both angiography and venography 3. It isn't perfect and has been found to overestimate stenosis when there is calcification close to the skull, additionally the presence of blooming artefact caused by calcifications can lead to artefacts in the post-processing too 3 . The term “dual-energy CT,” or “DECT,” refers to CT that uses two photon spectra; therefore, DECT is sometimes also referred to as “spectral CT.” In clinical practice today, two different spectra are generated either by switching the voltage of one x-ray tube or by running two tubes at different voltages, and spectral information is gained from two absorption measurements with normal CT detectors. Dual and multi-energy CT would be essential in diagnosing affected persons, and curb the mortality rate.
