The original GSI from the 750HD has been improved and integrated into the Revolution series as GSI Xtream. Revolution CT scanners are the first to include this technology. Visit us: http://www.siemens-healthineers.com/dual-source-ct-ytDual Source CT Dual Energy spectral imaging allows you to cover large anatomical volumes at hi Purpose of Review To explain the technique of Dual-energy CT (DECT) and highlight its applications and advantages in head and neck radiology. Recent Findings Using DECT, additional datasets can be created next to conventional images. In head and neck radiology, three material decomposition algorithms can be used for improved lesion detection and delineation of the tumor.

For patients who have had joints replaced, there is better imaging of the bone and soft tissues because the dual energy is used in conjunction with metal artifact reduction software. White Paper of the Society of Computed Body Tomography and Magnetic Resonance on Dual-Energy CT, Part 1: Technology and Terminology J Comput Assist Tomogr . Nov/Dec 2016;40(6):841-845.

dual-energy CT has been applied in many clinical areas, including automatic bone removal, stone composition characterization, virtual non-contrast imaging, diagnosis of gout, and assessment of myocardial blood supply. All these clinical applications require dual-energy processing to obtain material-speciﬁ c information.1,2

In head and neck radiology, three material decomposition algorithms can be used for improved lesion detection and delineation of the tumor. Iodine concentration 2020-09-11 · Background Dual-energy CT (DECT) can acknowledge differences in tissue compositions and can colour-code tissues with specific features including monosodium urate (MSU) crystals. However, when evaluating gout patients, DECT frequently colour-codes material not truly representing MSU crystals and this might lead to misinterpretations.
