Dual‐Energy CT (DECT) The fundamental principle behind the use of DECT is to differentiate materials based on their relative absorption of X‐rays at different photon energy levels (typically at 80 and 140 kVp). Ideally, the materials to be differentiated should be simultaneously imaged at the two different energy levels.

Department of Radiation 11 Mar 2019 However, so far no studies investigated the performance of these MA or DL methods on dual-energy CT (DECT) datasets, which have been INTRODUCTION. As dual-energy CT scanners become more common, it is worth revisiting their benefits over conventional CT. The promises to increase the 31 May 2019 From April 2019 onwards, they are implementing a novel, patient-specific method of proton range prediction based on dual-energy CT (DECT). 11 Sep 2020 DECT has diagnostic potential in gout as it can automatically colour-code MSU depositions, based on predefined software settings. The Dual energy CT can be used as a problem-solving tool in brain and spine imaging.

Dual Energy is built into all of our CT platforms, delivering fast, confident spectral imaging for your entire patient population, and virtually any clinical application, organization, and budget. It’s always ready for the right patient at the right time, right when you need it.

Dual energy CT offers the potential to analyze material composition through image acquisition at two different energy levels. In contrast to traditional single source multi-slice CT (Fig 1), a Dual Source CT (DSCT) is equipped with two data measurement systems, each consisting of one X-ray tube and one corresponding detector array oriented in the gantry with an angular offset of 90 degrees (Fig. 2). 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?

Dual-energy CT or multispectral CT is becoming increasingly more common in clinical practice due to the rapid rise in computer technology and expanding literature exhibiting vast advantages over conventional single energy CT.
