Gemstone Spectral Imaging (GSI ) is a dual-energy scan mode that acquires data Imaging of acute pulmonary embolism using a dual energy CT system with 

The dual-source CT scanner is composed of two x-ray tubes and two Dual-energy CT Protocols Lifeng Yu, PhD, FAAPM Professor of Medical Physics Department of Radiology, Mayo Clinic, Rochester, MN Outline Basic principle of dual-energy CT Major components of dual-energy CT protocols Major considerations in dual-energy CT protocols –Radiation dose –Scan techniques and spectrum selection 2016-05-06 · Compared with the conventional polychromatic imaging, monochromatic images reconstructed with adjusted energy levels provide improved beam-hardening correction, CT attenuation and CNR. 31,32 Theoretically, dual-energy CT with low energy levels can improve the contrast for vessels via exploiting the K-edge phenomenon when using CM, and the lowest energy level yields the “brightest” iodine Dual Energy CT（以下DECT）は、2種類の管電圧を用いた撮像ができるCTです。 2種類の管電圧を使用するための機構は、装置（メーカー）によって異なります。今回はその機構についての説明です。 昨今の流行でもあるDual Energy CT。 Dual Energyと略して呼ぶことが多いですが、ここではDECTと略します。 CTに関する学会の演題も、大半が 逐次近似再構成法の話かDECTの話 、と言っても過言ではないでしょう。 今回は、そのDECTについて基礎的な部分を解説します。 This, in turn, allows near-simultaneous dual-energy projections, minimizing the effect of organ and patient movement. 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.

Dual-Energy CT: Oncologic Applications in the Lung. Lung nodules—Lung cancer is one of the most common malignancies in both developing and developed countries and is also one of the leading causes of mortality worldwide . The most common initial manifestation of lung cancer is a solitary pulmonary nodule (SPN) smaller than 3 cm in diameter.

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 Dual-Source Dual-Energy CT • A SOMATOM Defi nition dual source CT scanner (Siemens Healthcare, Forchheim, Germany) was used to acquire images on all patients.

A dual energy CT scanner is fairly new technology that uses both the normal X-ray and also a second less powerful X-ray to make the images. This gives dual energy CT additional advantages over standard CT for a wide range of tests and procedures (see benefits of dual energy CT below). Why would my doctor refer me to have this procedure?
