syngo Dual Energy Xenon1,2


This new application uses Dual Energy information to visualize Xenon concentration in the lung without use of an additional non-contrast scan. A first step performs a material decomposition into Xenon and soft tissue; the Xenon concentration in the air inside the lung is calculated. The results are shown in a second step as color overlay to anatomical, grayscale information. 


syngo Dual Energy Xenon requires syngo® Dual Energy available on SOMATOM Definition Flash.

Eigenschaften & Vorteile

With the application syngo® Dual Energy, it is possible to obtain additional information about the chemical composition of body materials. During a Dual Energy scan, two CT datasets are taken simultaneously with kV levels of 80 kV/140 kV or 1100 kV/140 kV, allowing to visualize differences in the energy dependence of the attenuation coefficients of different materials.

These images will be combined and analyzed to visualize information about anatomical and pathological structures.
