syngo.via VA30 - CT Dual Energy Virtual Non Contrast VNC

syngo.via® CT Dual Energy Virtual Non-Contrast (VNC) The syngo.via Dual Energy VNC application class allows you to visualize the contrast agent concentration in the liver without an additional non-contrast scan. The application class generates virtual non-contrast (VNC) images by subtracting iodine from the Dual Energy data sets. The VNC images can be used for baseline density measurements. 1. From the Patient Worklist, load an appropriate data set into the Dual Energy Workflow.  If the examination has been correctly mapped, double click to load  If manual mapping is required, right-click the examination and select (Re-) Assign Workflow Template > CT Dual Energy 2. From the Workflow Steps, click on the Liver VNC Application Class. Body Bone Removal 3. syngo.via will apply a colored overlay map to the MPR images in Segments 1, 2, and 3, and will also generate a mixed DE image in Segment 4 (depending on selected layout). The overlay images display the iodine enhancement in the mixed image in Hounsfield units. SIEMENS www.usa.siemens.com/healthcare 643 Effective date 9/8/2016 Page 1 of 3 4. Hover over the bottom center of a Dual Energy overlay image to access the Mixing Ratio mini-toolbar. The slider allows you to control the composition of the displayed fused images. Depending on the slider position, either more CT data or more overlay data is displayed. Move the slider to the left to display more CT image data with the colored overlay (iodine enhancement) removed. This is a DE virtual non-contrast image of the contrast-enhanced source images.
