doi: 10.1097/RCT.0000000000000531. : Dual-energy CT in a patient with COVID-19 pneumonia without evidence of pulmonary emboli. Patient 1, an 87-year-old woman with a history of fever and cough for 5 days, was found on the floor of her nursing home. On admission to hospital, the patient required a non-rebreather mask with a flow rate of 2020-01-17 · All radiographic examinations were performed using a single source dual-energy CT system (Discovery CT750HD, GE Healthcare, Milwaukee, WI, USA) with 64 detectors and a scan field of view of 32 cm.

DECT acquisition techniques and subsequent post-processing can provide improved qualitative analysis, allow quantitative imaging, and have the potential to decrease requisite radiation and contrast material doses. a dual-source CT (Siemens Healthcare), by ultra-fast kVp switching in a single source CT (GE Healthcare) or by compartmentalization of detected X-ray photons into energy bins by the detectors of a single-source CT operating at constant kVp and mA settings (Philips Healthcare). 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.

In a DECT scan, projections are acquired at 140 kV (orange solid line) and 80 kV (green dashed like) alternatively at every 0.2 milliseconds.

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.
