syngo.via CT Cardiac Function

syngo.via® CT Cardiac Function syngo.via CT Cardiac Function is designed to aid in the diagnostic evaluation of cardiac CT angiography (CTA) multi-phase volume data sets, specifically in the assessment of the right and left ventricles for cardiomyopa-thy. 1. From the Patient Worklist, load an appropriate data set into the CT Cardiac Function Workflow: • If the examination has been correctly mapped, double click to load • If manual mapping is required, right-click the examination and select Open With > CT Cardiac Function 2. Use the Phase Navigator to review different phases in a multi-phase car- 80% 256 * 256 diac data set. Select a phase directly from the list, use the mouse (scroll 10% 256 * 256 wheel + ALT, or drag left/right + RMB) or up/down arrows to step through 20% 256 * 256 35% 256 * 256 consecutive phases. The cine mode will automatically navigate through 45% 256 * 256 50% 256 * 256 all available cardiac phases. The automatic loading strategy utilizes 55% 256 * 256 Best Diastole/70% R – R, or that phase which is closest. 60% 256 * 256 65% 256 * 256 70% 256 * 256 71% BestDiast 512 * 512 3. Review the preprocessing results. If needed, modify the heart chamber 75% 256 * 256 segmentation. 80% 256 * 256 • Display contour lines – in the Case Navigator, enable the Show Contours icon and evaluate the preprocessed contours Show  Red = LV endocardium, green = LV epicardium Contours  Yellow = RV • Manually initialize heart chamber segmentation – in some instances of complex pathological anatomy, the automatic segmentation may fail. In the Case Navigator, Initialize enable the Initialize Manually icon. Using the provided graphic as a guide, click to Manually identify two LV base points and the LV apex point. Chamber contours are recalcu- lated.

To better assess myocardial movement or the function of the aortic and mitral valves, MPR views can be aligned with the cardiac or valve planes. • In the Case Navigator, enable the Cardiac Planes icon.

Functional analysis of the left ventricle (LV) – including ejection fraction, stroke volume, and wall mo- tion - can be accomplished through either the Standard Mode or the Blood Volume Mode  The default Standard Mode calculates the LV volume within the red contour to include the papillary muscles and also uses a straight mitral valve plane.  The Blood Volume Mode calculates the LV volume indicated by the pink over- lay to exclude the papillary muscles and includes the aortic outflow tract by using an anatomically modeled valve plane.  On the Left Ventricular Analysis step, enable the Blood Volume Mode icon. • The LV Blood Volume can be edited to include or exclude more or less blood pool using the Blood Pool Threshold mini tool bar Blood Pool Threshold SHU -100 400 242 HU Unrestricted 0 Published by Siemens Healthcare GmbH © Siemens Healthcare GmbH, 2020 SIEMENS Master Template Effective Date: 3/5/2020 | HOOD05162003074494 Job Aid Effective Date: 4/28/2017| HOOD05162002591125 Healthineers Page 3 of 6 Job Aid | syngo.via CT Cardiac Function Effective Date: 4/28/2017| HOOD05162002591125 6.
