syngo.via VA30 - CT Dual Energy Brain Hemorrhage

syngo.via® CT Dual Energy Brain Hemorrhage The syngo.via Dual Energy Brain Hemorrhage application class extracts contrast medium (iodine) from DE brain CTA datasets. This provides an iodine distribution/ enhancement map of the brain parenchyma. The application helps differentiate new blood within a resolving hemorrhagic site. 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 Brain Hemorrhage Application Class.

The overlay images display the iodine enhancement in the mixed image in Hounsfield units. SIEMENS www.usa.siemens.com/healthcare 642 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. This image may be windowed using the middle mouse button over the right half of the image segment. Move the slider to the right to display more iodine data in the image.

In this clinical example, the color overlay image shows an area of hyper-dense iodine concentration within the existing hematoma, possibly indicating a new bleed within the old hematoma bed. 6. This resulting VNC data set may be saved as a new axial, coronal or sagittal series using the Parallel Ranges tool in an upper left colored overlay segment.
