You will not notice any difference in the examination whether you have a single energy or dual energy CT. Are there any after effects of a dual energy CT scan? Dual energy CT itself is not associated with any immediate after effects. In the sequential acquisition dual-energy CT approach (Volume Dual Energy; GE Healthcare, Milwaukee, Wis), the system operates in axial mode allowing the acquisition of two CT scans at fixed-energy spectra—140 kVp and 80 kVp—at the same anatomic level .

Three types of dual-energy CT scanners are available that differ in the technique used to acquire high- and low-energy CT datasets: a dual-source dual-energy scanner, a single-source dual-energy scanner with fast kilovoltage switching (ie, rapid alternation between high and low kilovoltage settings), and a single-source dual-energy scanner with dual detector layers. 2021-02-17 · The dual-energy acquisition method with the GE scanner involves a rapid kilovoltage-switching technique, in which a single x-ray tube switches the tube energy every 0.5 ms from 80 to 140 kV during the same tube rotation. 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.

While the concept of Dual Energy CT was introduced by Siemens more than 30 years ago with fast kV switching on the SOMATOM DRH 1, it wasn’t until about 10 years ago that Siemens Healthineers was able to bring Dual Source Technology to the clinical market and with it a more advanced way of acquiring spectral data - Dual Source Dual Energy.
