Download and print a copy of the Course Review. General improvements in MR workflows In this chapter, we explained general improvements in MR workflows. These improvements include: The display of series numbers in the series navigator: now the series navigator combines the display of the data role and the numbering of series.  ​Flashing of patient tabs: the patient tabs flash to attract the user's attention if a workflow in the background requires any action from the user. ADC/b-value preprocessing: you can now calculate the ADC/b-value during preprocessing. "Save as Series": this new function enables you to save your series with user specific settings. Copy/Paste Measurement: there are several improved functionalities which enable you to copy and paste measurements to the same segment or to the cursor position. Measurements can be copied and pasted to another segment. Please be aware that the name of this function changed from "Paste Measurement" to "Paste to same organ positon". MR Basic / MR Cardiac In syngo.via VB30, the handover of findings/results is improved. If you are already working on a study when new results arrive, you will be informed by a message if the new results shall overwrite the existing results or if the new results shall be discarded. ​ MR Angiography - new workflow The new workflow MR Angiography combines the previously existing workflows MR Angio Single Station, MultiStation, TWIST, and TimCT. MM Reading - 4D Viewing tool The 4D viewing tool is optimized for temporal navigation. With the help of the tool, you can define phases with clinical relevance or assign labels and colors to clinically relevant phases. In addition, you can divide the total number of series in clinically relevant phases to get quick access to the series with the help of the tool. MR Onco/mMR - new SUV unit In MR Onco/mMR, a new SUV unit "SUV-Lbm (Janma)" is now available for the MR Pet Series. The SUV unit is located in the lower corner menu under "Units". MR OncoCare - Histogram source and settings For calculating a histogram of the defined region you can use any ROI, VOI or segmentation. Based on that you can display a graphical representation of the distribution of data for that region. In addition, this can be applied to 2D and MPR images. MR Neurology In this chapter, we talked about Brain Morphometry and settings of this workflow within MR Neurology. For the display of Brain Morphometry results, there is no dedicated layout. The results have to be loaded from the series navigator into the viewing area. The results are label map, deviation map as well as a combination of both maps fused with MPRAGE and report.  There is a dedicated Brain Morphometry tab in the workflow configuration which allows you to define special settings regarding the creation of results and regarding the automation of sending results to the PACS (function "Send to PACS") without any user interaction.  MR Neuro 3D Reading - Freehand ROI for Tractography By selecting the interactive mode in Tractography, you can use a Freehand ROI to define the individual seed points. MR Cardiac Analysis  In this chapter, we explained new features and improved functionalities of the MR Cardiac Analysis workflow. In syngo.via VB30, you can now choose between two different modes in MR Cardiac Analysis Function: normal (segmentation and placement of landmarks is done automatically during preprocessing as in previous versions) and manual (no preprocessing is done, the user can create contours and landmarks manually). The functionality MR Cardiac Function Properties enables you to define if the normal or manual mode is active when the application MR Cardiac Analysis is started. In addition, a new freehand editing tool is included in syngo.via VB30. This tool enables you to edit existing contours of the left and right ventricle by drawing a freehand line. By doubleclicking the action will be finalized. Furthermore, the tool provides you suggestions for deleting parts of the contour with a dedicated mouse pointer. In Finding Details, the new syngo.via software version now allows you to save the data from the result table also as text. Therefore, just select “Save as text”. The current status of the MR Cardiac Analysis workflow can be saved and restored. Go to “Finding details” and select “Export Result Images/All” to create a finding. By closing the MR Cardiac Analysis workflow with “Save” and sending the images to another server to open them again, the system will preprocess the cardiac images and produce new contours. MR Tissue 4D In this chapter, we explained several improvements to the MR Tissue 4D workflow. The workflow MR Tissue 4D can also be used for other organs or body regions.  A color scale bar is now available in the segments that are displayed in the parametric maps. Interoperability In syngo.via VB30, the interoperability was improved regarding the MR Breast workflow. This means you can now use some additional GE and Phillips data for post processing. ​   Handover of Findings/Results - only applicable if you have a MAGNETOM Vida scanner While evaluating images in an Advanced Viewing application on Vida results, e.g. distances and markings, ROIs can be generated. Select "Save" to store and send the results to your via server. You can open and modify these results in the same workflow on the syngo.via server.  If results already existed for the same study on syngo.via, the new results will be added to the study and/or results that already exist will be adapted. If you already have the study open while the results are arriving you will get a message asking if the results that arrived most recently shall overwrite the already existing results or if the most recent results shall be discarded. The result handover is possible for results that are generated in MR Basic and MR Cardiac Analysis (for MR Cardiac results please take a look at the page MR Cardiac Analysis > Save and Restore). All in one workflow In syngo.via VB30, there is now only one common Angio workflow available: MR Angiography. This workflow combines the previously existing workflows MR Angio SingleStation, MultiStation, TWIST, and TimCT. It includes the functionalities and layouts from the previous workflows.   In syngo.via VB30, MM Reading provides a special 4D viewing tool that is optimized for temporal navigation. This 4D viewing tool is very useful for the temporal navigation of multi-phases data, e.g. GRASP. The tool illustrates the clinically relevant phases. With the help of the tool you can navigate efficiently to the clinically relevant phases. In addition, the tool enables you to divide the total numbers of series in clinical relevant phases and to access the series quickly.   New SUV unit For MR PET series, the new SUV unit "SUV-Lbm (Janma)" for obese patients is now available, where SUV is calculated using lean body mass (Lbm). It is accessible in the lower corner menu under "Units". Histogram source and settings You can use any ROI, VOI or segmentation to calculate a histogram of the defined region to display a graphical representation of the distribution of data for that region. This can be applied to 2D or MPR images. In addition to the statistical values left percentage, middle percentage, right percentage and mean, the median value will be displayed in the histogram segment as well. Furthermore, the values of the left and right slider position will be displayed. You can also select the median value in the trending Metric of the Findings Navigator. In Edit Settings, accessible via the tool panel, you can define the scaling of the axis. You can configure the y-axis to display the absolute frequency in counts or the relative frequency of percentage of all voxels.     The "Brain Morphometry" calculations are optional licenses integrated in the MR Neurology workflow. The feature allows you the segmentation and volume calculation of the different brain areas. You can compare these results with normative values from a standard group. In addition, a report will be generated. The scan data for this evaluation needs to be a specific strict scan T1 MPRAGE protocol. This protocol is provided in the Siemens protocol tree (SIEMENS/head/advanced applications/morphometry). If the input data does not follow the preconditions the system will inform you (by generating a result series showing an error description).   In Neurology settings there is a dedicated Brain Morphometry tab to define the following special settings: "Send to PACS": If you select yes, after the calculation, the result images will be sent directly to PACS without any user interaction. If you select no, the result images will be saved and available on syngo.via. You can send the images to PACS manually or by selecting "Save and Send" when closing the workflow.   Disable processing of improperly acquired image data: If you select checked, then only data that fully conforms to the protocol can be used for calculation. If you select not checked, then also other data will be used for calculation. You will be informed by the system about that by a dedicated note in the report.   Freehand ROI for Tractography If you have selected the interactive mode in Tractography, you can use a Freehand ROI to define the individual seed points.     Syngo.via VB30 allows you to select between two different modes in MR Cardiac Analysis Function: Normal – the segmentation and placement of landmarks will be done automatically during preprocessing as in previous versions. Manual – no preprocessing will be done. The user can create contours and landmarks manually. You can switch between normal and manual mode at any point in time during the workflow. e.g. LV results can be obtained with normal mode and the results can then be compared with RV results obtained in manual mode. It is also possible to switch between the modes in the evaluation step. Manual mode has the same support tools, edit tools, and delete tools as in normal mode. No propagation of contours is available in the manual mode. In manual mode the cardiac landmarks, (e.g. apical extent, blood pool), will not be displayed. But if data is loaded into the long axis segments it is possible to define the base plane on the loaded long axis slices by setting landmarks. In “MR Cardiac Function Properties” you can define if the normal or manual mode shall be active when the application MR Cardiac Analysis is started. This setting is user specific.   In syngo.via VB30, the new Freehand editing tool allows you to edit existing contours of the left and right ventricle by drawing a freehand line that intersects at least twice with the existing contour. If you double-click, the action will be finalized and the defined part will be deleted. If you are unsure which part of the contour shall be deleted, the system provides an indication with a dedicated mouse pointer. You can now decide which part shall be deleted with a click. Move the mouse to mark the line blue. Click to delete parts according to this blue line. In addition, you can replace an existing contour completely by drawing a closed freehand contour, that does not intersect with the existing contour without having to select a different tool.   In Findings Details you can save the data from the result table as text for reporting purposes. If you select “Save as text” the content of the result table will be saved.   Syngo.via VB30 allows you to save and restore the current status of the MR Cardiac Analysis Function workflow. Open "Findings details" and select "Export Result Images/All" to create a finding. The system will store the previously defined contours, results, and respective result images in the result section of the series navigator. If this is done several times with different contouring statuses, you will get results for every status in the series navigator.  If you drag and drop these respective result images from the series navigator to the image area, the status of the analysis is restored and can be resumed. You can now continue with the contouring process or adapt the contour. If you close the MR Cardiac Analysis workflow with "Save" and send the images to another server to open them again, the system will preprocess the cardiac images again and produce new contours. If you want to access the previously stored contours, you can load them from the series navigator and the work will be resumed.     Syngo.via VB30 now allows you to use wildcards (*) for input data definition in the properties of the MR Tissue 4D workflow. This makes it easier for you to define the right DIXON sequences for processing. e.g. Vibe *W.    In general, the workflow MR Tissue 4D is used for the evaluation of contrast media behavior in the prostate. Nevertheless, you can also use the workflow for other organs or body regions. You just need to adapt the preprocessing settings to different organs.   Go to the Clinical configuration in the administration portal to generate a copy of the MR Tissue 4D workflow. Then assign the copied and renamed workflow to the specific body region data. Now you can define the preprocessing data, (e.g. pharmacokinetic model, type position of VOI, maps etc.) for the organ. If you want to evaluate multiple body regions, you can define, rename and adapt multiple copies of MR Tissue 4D.     In syngo.via VB30, the segments displaying the parametric maps will now include a color scale bar.   In syngo.via VB30 the MR Breast and Neuro3D (Offline DTI) workflow now allows you to use some additional GE and Philips data for post processing.   syngo.via VB30 provides several improvements with regards to MR workflows. The improvements consider: the display of series numbers in the series navigator glowing of patient tabs ADC/b-value preprocessing "Save as Series" Copy/Paste Measurement Learn more about the improvements on the following pages. In syngo.via VB30, the series navigator now also displays the series number additionally to the existing information. In syngo.via VB30 inactive patient tabs will indicate required user attention by glowing.   In syngo.via you can already calculate the ADC/b-value during preprocessing. Open the Analysis ADC/b-value tool from the lower right corner menu. Select the gear-wheel to open the ADC/b-value preprocessing tab. Check mark “Enable preprocessing” to enable the preprocessing. Define the expected output b-value, the threshold for noise filtering and minimum number of input b-value that are required for triggering the preprocessing calculation (by default the value is 2). The preprocessing is executed during the assignment of a workflow in which the ADC/b-values tool is implemented, e.g. MR Basic, MR Onco, MR Breast etc..     In syngo.via VB30 there are several improvements regarding the Copy/paste measurement.  In general, when you define a measurement in one segment, you can now paste the measurement in the same segment, but on a different slice or in the same segment on the same slice but at a different position. The details of the functionalities are: "Copy/Paste Measurement to same Segment": After copying any 2D measurement scroll through the current segment to another frame. In this new frame it is possible to enter the “Context Menu” (by right-clicking the segment). Select “Paste on the current image”. The copied graphic will appear at exactly the same position as on the original frame. "Copy/Paste to the cursor position": After copying any 2D measurement move the mouse cursor to a new position within the segment. Enter the “Context Menu” (by right-clicking on the segment) and select “Paste to the cursor position”. The copied graphic will appear at the current mouse cursor position. “Copy/Paste Measurement to another Segment”: There are no changes in this functionality; only the name of the entry in the context menu has changed to “Paste to the same organ position” instead of “Paste Measurement”. In syngo.via VB30 MR Neurology offers a new functionality with Brain Morphometry. Learn more about general and special settings of Brain Morphometry from the following pages.

Copyright © Siemens Healthcare GmbH, 2018 The new functionality "Save as Series" enables you to save the current display state of a series (e.g. the current windowing or with user-defined measurements). The results will be available in the result section of the series navigator. For example in MR Neurology, the functionality "Save as Series" enables you to save your individual adjustments for parametric maps. In the segment where a perfusion is displayed, select an MR Color LUT from the lower right corner menu and window the images as needed. Choose "Save as Series" from the upper left corner menu. A new series with the defined settings is saved in the result section of the series navigator. If you would like to view the series PACS, the images will be displayed with the saved color LUT and window values.     If the licenses are available and a study will be assigned to MR Neurology, the results for Brain Morphometry will be automatically calculated and visible in the series part of the browser. In addition, you can open and view the results in syngo.via or you can send the results directly to PACS for viewing. You can configure whether or not the results are sent directly without any user interaction to the PACS. In general, there is no dedicated layout for displaying the results of Brain Morphometry. Therefore, the results have to be loaded from the series navigator into the viewing area. The results are: Label map (segmented brain regions in dedicated colors; explanations for colors are given in the operator manual), Deviation map (comparison of segmentation with normal range. Any deviation from the normal range will be marked in red), a combination of labeled and deviation map fused with the MPRAGE series, Report (results for all brain regions as numbers where any deviation will be marked).   In syngo.via VB30 MM Reading provides a special 4D viewing tool. Learn more about the 4D viewing tool from the following pages. When you work with NumarisX systems, e.g. MAGNETOM Vida, you can define and label the phases during scanning.  This information will be handed over to syngo.via and used for the 4D viewing tool. In addition, the labeling of phases will be done automatically for GRASP in NumarisX systems. Time points are displayed on the time axis for the phases with clinical relevance. The color of the time points corresponds to the color that is assigned to the respective phase. If the current phase has a label, the label of that phase is shown above the selected time point in that phase. By clicking the time point of a clinically relevant phase you can navigate to the respective phase (see second screenshot on the right). In addition, you can choose to hide the lower part. You can configure whether or not this part is visible at the beginning or use the arrowhead between the upper and lower part to hide/show the lower part.
