We understand that you want better clinical answers, more confident decisions, and most importantly, early diagnoses. You want a CT solution that gets it right the first time, is easy to use, and is able to serve your entire patient population.
Discover Dual Energy (DE) spectral imaging. It’s the difference between images and answers. Visualization and characterization. Qualification and quantification. Built into all of our CT scanners, it delivers powerful performance, incredible versatility for your entire patient population, and exceptional ease-of-use – all while integrating seamlessly with your current workflow.
And that is a world of difference.
What is Dual Energy?
Beyond images, answers.
See how Dual Energy compares to conventional CT.
Why are healthcare leaders choosing Dual Energy spectral imaging over conventional CT? It’s simple. Dual Energy offers you everything you expect from conventional CT, transformed to deliver more value for your entire patient population.

More than a feature, the future
See the future of healthcare.
See what truly information-rich spectral images can mean for you and your patients.
Siemens' Single Source and Dual Source Dual Energy techniques impress radiologists with their easy-to-use scan protocols, their suitability for daily clinical routine, their range of applications, and their scientific validation (more than 150 scientific publications).
Maximize image quality with Monoenergetic Plus
Allows users to display monoenergetic images for a range of 40–190 keV. By displaying multiple monoenergetic ROIs and the associated absorption curves, Monoenergetic Plus lets users easily compare and quantify lesions and tissues.
The ability to export statistical information into the file system for further evaluation is very beneficial for various research and diagnostic tasks.
Quantify lesions with two scans in one
syngo.CT DE Virtual Unenhanced assists you in visualizing the contrast agent concentration in the liver. The basis for this approach is a material decomposition into iodine contrast agent, fat, and liver tissue. You can also create virtual non-contrast information using the Dual Energy information from fat and liver material. You can switch between these two representations of the anatomical information without the need for an additional non-contrast scan.
Accurate bone removal even in complex body regions
With syngo.CT DE Direct Angio, you can overcome the limitations of conventional bone removal software. The Dual Energy approach reliably isolates even complex vasculature, for example, at the base of the skull where CTAs are difficult to interpret.
Assessment of perfusion defects and affected vessels at a glance
Perfusion defects in the lung are often caused by pulmonary embolism. The application syngo.CT DE Lung Analysis enables the color-coding of vessels that are affected, for example, by pulmonary emboli. It also allows a fast evaluation of lung perfusion defects at a glance without requiring an additional non-contrast scan.
Differentiate hemorrhage from iodine-uptaking bleedings and lesions
The Dual Energy application syngo.CT DE Brain Hemorrhage assists you in visualizing iodine concentration and distribution in the brain. Lesions and bleedings may show significant iodine uptake in the image, while inactive hemorrhages are not enhanced.
Reveal perfusion defects with only one scan
With syngo.CT DE Heart PBV, you can visualize the iodine concentration and distribution in the myocardium to reveal perfusion defects. In addition, you can use a virtual non-contrast display to identify myocardial edema. The simultaneous acquisition of high- and low-kV datasets diminishes the problem of misregistration due to cardiac motion.
Overcome the limitations of diagnosing gout
The diagnosis of gout is not always simple – for example, in acute cases where an aspiration cannot be performed. Nor is the uric acid concentration in the blood always a reliable indicator. syngo.CT DE Gout overcomes these limitations by quickly, noninvasively, and accurately visualizing uric acid crystals. This spares your patient a painful and stressful examination.
Characterization of kidney stones
Kidney stones contain varying amounts of heavy atoms (for example, uric acid stones versus non-uric acid stones). Dual Energy CT can be used to perform a differentiation of these materials. With syngo.CT DE Calculi Characterization, you can visualize these chemical differences in kidney stones and use the information for your therapy decision.
Types of Dual Energy
Which solution is right for you?
Regardless of your unique challenges, Dual Energy spectral imaging offers a transformative CT advantage. Both Siemens Healthineers solutions help you visualize differences in the energy-dependence of the makeup of your patients, revealing critical information about anatomical and pathological structures.
- During a Dual Source Dual Energy scan, two CT datasets are acquired simultaneously with different kV and mA levels, allowing you to visualize differences in the energy-dependence of the attenuation coefficients of different materials. These images are combined and analyzed to visualize information about anatomical and pathological structures.
- Available for SOMATOM Definition Flash, SOMATOM Drive, and SOMATOM Force
- TwinBeam Dual Energy (TBDE) allows simultaneous acquisition of high and low kV datasets in a single spectral CT scan by splitting the X-ray beam with two filters before it reaches the patient, enabling high-contrast dynamic applications
- Available on SOMATOM Edge Plus, SOMATOM Definition Edge, and SOMATOM go.Top
Dual Energy, differentiated
While there are lots of spectral imaging solutions out there, only one is the most clinically-tested. And only Dual Energy delivers on all three critical fronts: performance, versatility, and ease-of-use for your entire patient population.
