syngo.via - CT Liver Analysis step by step

syngo.via® CT Liver Analysis syngo.via CT Liver Analysis supports diagnostic evaluation of the liver, its lobes, and its intrahepatic vessel struc-tures. It helps to identify the vascular territories of sub-vessel systems and enables volumetric measurements of the complete liver, liver segments, and tumors. This is especially helpful in the pre-surgical planning of liver donors and oncological resections. 1. From the Patient Worklist, load an appropriate data set into the CT Liver Analysis 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 Liver Analy- sis 2. Phase Selection - up to six different phase volumes are automatically assigned to different segments based on DICOM header information: • Liver (LIV) – venous phase or most contrasted se- ries • Tumor (TUM) – arterial or venous, depending on tumor type • Portal Vein/Portal Venous (PV) • Hepatic Vein (HV) • Hepatic Artery (HA) • Bile Ducts (BD) or Magnetic Resonance (MR) • Move or add series from the series navigator by man- ually dragging and dropping with the left mouse but- ton (LMB) into the desired segment. Note that the same series can be allocated to multiple segments. Phase Selection • Click the Finalize Phase Selection icon to confirm phase selection and automatically begin pre-processing.

Note: 3D editing enables corrections to the volume (current slice and neighboring slices), while 2D editing provides fine tun- ing of the current slice contour only.

The Lesion Segmentation step is optional, and only active if a CT phase was assigned to the Tumor (TUM) segment. Draw a Lesion Segmentation OH straight line across the lesion and the semi-automatic seg- mentation algorithm starts. Contours can be modified using Reset the tools in the mini toolbar and the results are sent to the Segment Lesion Findings Navigator.

In the Vessel Segmentation, you can semi-automatically segment up to four vascular anatomies based on the CT phases previously defined for the HV, PV, HA, and/or BD segments. The Vena Cava can also be segmented semi-automatically. From the Case Navigator, select the vascular anatomy you wish to segment first. • Using the provided graphic as a guide, click in the desired anatomy. Vascular segments can be added, removed, split, or otherwise modified using the tools provided. Vessel Segmentation HV PV . HV. PV .

In the Vascular Territories step, vascular anatomy is further classified into territories based on the prior vessel segmentation. Select each segmented vessel and label the vascular tree in the MPR or VRT. Labels are displayed in the mini toolbar, each with its own color. Vascular Territories .

The Virtual Planning step allows for a virtual resection of the liver to help simulate surgical planning. There are three default proposals, or alternate proposals can be defined by drawing a contour in the MPR or VRT segments. • Using the Object Navigator, you can show or hide the volume of all segmented structures to display relationships between anatomies. • The report and results series are saved and archived by completing the workflow with the Save and Send button Presets Virtual Planning Proposal 1 Proposal 2 .
