True Dual Energy with Single Source CT


Single Source Dual Energy

DEfinitely Siemens

More and more radiologists count on Dual Energy for its rich diagnostic possibilities. The key question is: What makes it True Dual Energy? Look for these three criteria:

  • Crisp images with the option for even sharper contrast and significant metal artifact reduction
  • Dose-optimized scans for Dual Energy 
  • Wide-ranging utility for virtually all clinical questions and all patients

If your daily routine includes highlighting, characterizing, quantifying, and differentiating material, don’t accept less. True Dual Energy offers the leading technology from those who pioneered it – and that’s DEfinitely Siemens.

True Dual Energy – the Single Source scan mode

During a Single Source Dual Energy scan, two CT datasets are acquired at different kV and mA levels using two successive spiral scans. The two spirals are performed consecutively in an automated procedure with high temporal and spatial resolution. This scan mode is available for the SOMATOM Definition AS family and the SOMATOM Definition Edge.

DEfinitely excellent images

True Dual Energy CT takes you to another level of diagnostic possibilities with your CT scanner by adding quantitative information to the morphology of a conventional CT scan.

This capability delivers valuable images for diagnosing conditions like gout.

True Dual Energy images offer you excellent image quality to enhance your diagnostic outcome. Both Dual Energy datasets are obtained with high temporal and spatial resolution. The Single Source scan mode also acquires a full number of projections, providing you with high diagnostic image quality in both datasets. As a result, monoenergetic Dual Energy images deliver a crisp and artifact-free anatomical view in even the most complex cases.

From the Single Source Dual Energy scan to the registration of the datasets, everything is designed to be easy to complete. There are no complex interactions in the scan process: for example, in the characterization of kidney stones, where you perform a non-contrast abdominal Dual Energy scan. 

DEfinitely the right dose

When multiple scans of the same region need to be performed, dose protection becomes very important in order to adhere to the ALARA principle. But at the same time, you don’t want to sacrifice image quality and diagnostic information. With True Dual Energy, you get all the advantages of Dual Energy imaging with an optimized dose.

The Single Source Dual Energy scan mode consists of two consecutive spiral scans. In order to avoid doubling the dose, both spirals are performed at approximately one-half the dose, so that there is no dose penalty to obtain the resulting high-quality image. This allows you to remain in compliance with the ALARA principle. And you don’t have to compromise in order to get both excellent images and the right dose.

To make an imaging modality useful for clinical routines, it is imperative to exploit every opportunity for reducing radiation dose. Following this philosophy, Siemens has introduced the only Single Source Dual Energy scan mode that utilizes all dose reduction functionalities without limitations. For instance, you can apply SAFIRE, the latest dose reduction technique, to reduce the tube current using iterative reconstruction.

DEfinitely versatile

Compliance with the ALARA principle allows you to tap the advantages of Single Source Dual Energy for literally all of your patients – including elderly and fragile ones. Dedicated scan protocols and evaluation software applications enable you to use True Dual Energy extensively for a wide variety of diagnostic challenges. Here are some examples:

  • Diagnose gout accurately and non-invasively with syngo.CT DE Gout
  • Reduce the impact of metal objects on image quality with syngo.CT Dual Energy including Monoenergetic imaging
  • Characterize kidney stones with syngo.CT DE Calculi Characterization
  • Quantify and differentiate cancerous liver lesions with syngo.CT DE Virtual Unenhanced
  • Differentiate hemorrhage from iodine-uptake bleeding and lesions with syngo.CT DE Brain Hemorrhage
