syngo.via CT Vascular

In many institutions, vascular CT is a well known routine tool for the evaluation of central and peripheral vessels. It is an essential tool in the diagnosis of life threatening diseases such as aortic dissection or pulmonary embolism, as well as the management of stent planning in patients with AAA. You benefit from clinical applications that support both seed and routine, which are essential in challenging cases. This movie shows you how to evaluate CT vascular datasets. As soon as you open CT vascular, it has preprocessed the images by removing the table and bones and segmenting and labeling the applicable vessels such as the aorta, the left and right runoffs, the renal arteries and the internal and external carotids. They will be displayed as curved planar reformations in a dedicated layout. Depending on the body region and the type of data set, dedicated algorithms are already chosen to mask out bones. You can optimize the automatic bone removal manually by activating the edit bones option. And then clicking on any area that you want to include in or remove from the mask. To finish editing and update the bone removal results, simply deactivate the edit bones icon. In the event of suboptimal results, you can also switch between algorithms using, for example, the structure isolation mode if you want to start a user defined bone mask from scratch, defining the areas to mask or unmask as in the edit bone removal mode. After checking bone removal, you might want to have a first look at the MPR segments. Notice that you can navigate by right clicking and dragging the mouse up and down, or by using the scroll wheel. You can also move or rotate the reference lines to look for a specific orientation. To enhance your workflow, the vessel surf tool allows immediate 3D navigation even without the existence of centerlines or in occluded vessels. The main vessels that have been detected are labeled and displayed as a CPR on the corresponding segments. This view is very useful because it shows the complete path of the vessel and its lumen in a longitudinal view and a cross-sectional view orthogonal to the center of the vessel. Navigation is simple. Just right click and drag the mouse horizontally over the CPR to rotate around the axis. In the vessel definition step you can find a set of semi automatic and manual tools. If you need to correct center lines or create additional center lines. To create additional center lines, for example to get a CPR of the mesenteric artery, try the multiple clicks mode. You just need to set a few points along the vessel. Tracing support will calculate the paths in between. Trying to follow the center of the vessel. You can set the points in any of the displayed segments on the MPRS on the VRT or even on the available CPRS. Rename your center line by double clicking the vessel name and editing it. To correct existing center lines, the functions control point, edit and freehand edit are available. The first mode allows you to modify the center line by moving, adding or deleting the control points that define the path of the vessel. With freehand edit you can manually redraw the path of the vessel as you wish. You can also extend an existing center line by clicking over the endpoint of a center line. Then add more points over the vessel with individual clicks and with a DoubleClick to finish. To see more editing options, right click the center line. In the following workflow step vessel evaluation you will find some tools if quantification is needed, for example for assessing the severity of a stenosis or planning stent placement. Click the stenosis measurement tool. Notice that you can also find it on the mini toolbar. That will activate three or two references depending on the properties of the tool. If two references are activated, drag the yellow one over the stenosis and drag the green one proximal or distal, before or after the stenosis. Minimum and maximum diameter are calculated for every reference and the stenosis ratio in area and diameter by comparing the lumen on the yellow marker with the green one. The distance between the markers shown at the bottom helps you determine the stent length. Click the create finding tool if you want to send the measurement to your findings navigator and for further archiving. For reporting purposes, it is also very convenient to create radial CR ranges located in the upper left corner menu. The interactive spectral imaging functionality allows you to display different representations of dual energy data by using the interactive image text that is available in the segments. To use the interactive spectral imaging functionality, you need to load a sectral postprocessing data set. When you initially load an app data set, the main representation is displayed. Available representations are conventional connect mixed mono plus VNC, iodine and pure lumen. You can choose one of them from the menu opened by right clicking on the current representation name on the left side of a segment. You can also switch the representation by clicking the current representation name on the left side of a segment. You can change the value of Kev in monoenergetic plus images by entering the value of Kev or by using a slider which can be shown by right clicking on the Kev on the left side of a segment. The pure lumen is only available for a specific vascular spectral post. Processing V data set from a quantum technology system. It shows only the lumen of the vessels by subtracting the calcium from the image.
