syngo.via - CT Coronary Vessel Evaluation

syngo.via® CT Coronary Vessel Evaluation syngo.via CT Coronary is a full-featured software package designed to aid in the diagnostic evaluation of car- diac CT angiography (CTA) volume data sets. CT Coronary Analysis provides general evaluation tools, vessel definition tools, and vessel evaluation tools that support in the identification and quantification of coronary lesions and other cardiac anomalies. 1. From the Patient Worklist, load an appropriate data set into the CT Coronary 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 Coronary 2. The Vessel Evaluation Workflow Step provides tools for measuring and CT Coronary quantifying lesions, stenoses, and other pathology found within the cor- onary vessels. There are also Radial and Parallel range tools for the re- is Isolate Coronary Remove Tree Blood Marker Heart porting and documentation of these findings.

To measure a stenosis, enable the Stenosis Measurement icon on the Case Navigator or in the mini toolbar of the CPR segment. A yellow stenosis marker and green and/or red reference markers will populate on the CPR. • Drag the markers up or down to the desired pathology in the vessel. Corresponding lumen contours – with area and diameter – will be dis- +343 5mm played in the cross-sectional segments. Stenosis length is calculated as the distance between the various markers [green text: distance between yellow marker and green marker; red text: distance between yellow marker and red marker; white text: distance between red and green markers]. • To store the current measurements as findings, click the Create Finding icon in the CPR mini toolbar.

To measure vessel diameter, enable the Vessel Diameter Measurement icon on the Case Navigator or in the mini toolbar of the CPR segment. A yellow-blue marker ap- pears in the CPR segment and the corresponding position is marked by a blue disk in the VRT. The measured diameter is displayed in the lower left corner of the CPR segment. Diameter • In the cross-sectional segments, the lumen contour is displayed and the LAD measured lumen area (A) and min/max diameter (D) are displayed as image text. • Drag the measurement marker up/down in the CPR segment or click along the vessel in the VRT to reposition the marker. • To store the current measurements as findings, click the Create Finding icon in the CPR mini toolbar or just click once over the yel- low/blue marker on the vessel. 60 mm 5. To measure vessel length, enable the Vessel Length Measurement icon on the Case Navigator or in the mini toolbar of the CPR segment. Green and red markers appear in the CPR segment representing the upper and lower borders of the measurement. Length • Drag the measurement marker up/down in the CPR segment or click along the vessel in the VRT to reposition the marker. • To show or hide the blue line that marks the measured section, click the Dis- tance label in the lower left corner of the CPR segment. • To store the current measurements as findings, click the Create Finding icon in the CPR mini toolbar. + MON CV |Distance: 52.8 mm Unrestricted 0 Published by Siemens Healthcare GmbH © Siemens Healthcare GmbH, 2020 SIEMENS Master Template Effective Date: 3/5/2020 | HOOD05162003074494 Job Aid Effective Date: 5/4/2017| HOOD05162002591122 Healthineers Page 2 of 4 Job Aid | syngo.via CT Coronary Vessel Evaluation Effective Date: 5/4/2017| HOOD05162002591122 6. To measure a stenosis with one click, enable the One Click Stenosis Measurement icon on the Case Navigator. • Click the vessel near the identified stenosis. Single • syngo.via automatically performs a one-click vessel tracing (if no centerline ex- ists), positions the yellow stenosis marker in the local lumen minimum around the initial click point, and positions the reference markers. 7. To create a series of radial CPR ranges, enable the Radial CPR Ranges icon on the Case Navigator. The window provides the following parameters: • Degree steps defines the angle between pairs of images • Image Comment defines text written into the DICOM header • Range Series Name defines the name of the result series Radial CPR • Modify the values as needed and click Start 8. To create a series of parallel CPR ranges, enable the Parallel CPR Ranges icon on the Case Naviga- tor. The window provides the following parameters: • Distance defines the distance between pairs of images • Image Comment defines text written into the DICOM header Parallel • Range Series Name defines the name of the result series CPR • Modify the values as needed and click Start 9. To modify lumen contours, enable the Edit Contour icon on the Case Navigator. In a cross-sectional segment displaying the lumen contour, double click the segment to expand it. • Click the starting point of the contour section to be changed. • Drag the mouse pointer to draw the new contour • Double click to end. Edit Contour • A new lumen contour is displayed with new values calculated.
