syngo.via CT Dual Energy Application Classes

Depending on the scan mode used and the licenses purchased, the available tools functions and the application classes of SINGO, CTT, dual energy are different. From the large portfolio of dedicated dual energy application classes in this movie, we will show you the following application classes liver, VNC, virtual unenhanced, monoenergetic plus. Direct angio, bone removal. Lung analysis. Gout. Kidney stones. Bone marrow. Hard plaques brain hemorrhage. Heart PBV rosy. Let's start with liver virtual noncontrast, liver VPNC. The contrast media uptake of a lesion can be an indicator for its malignancy. And therefore in oncology, a series without contrast media is always recommended. However, with dual energy it is possible to view a virtual noncontrast image to locate the tumor without the need for an additional scan. The fused image displayed shows a combination of the VNC data and the iodine uptake. You can interactively change the mixing ratio of both data. Or visualize both simultaneously with a side-by-side layout. If you activate the extended region of interest text and create a region of interest in the lesion, you will notice that liver VBNC can also help you to accurately measure the iodine uptake milligram per milliliter in liver tissue and lesions. Furthermore, information about the VNC Hounsfield units value and the contrast media uptake in Hounsfield units is also available, together with the content value of the low and high KV and the mixed datasets. Even the concentration of fat is calculated and can now be displayed as a fat map from the layout gallery. The application class virtual unenhanced is very similar, but optimized for other organs with a lower content of fat than the liver, such as the lungs, kidneys and pancreas. The virtual unenhanced application class creates virtual noncontrast VNC images by subtracting iodine from the datasets. This allows you to visualize organs that contain only minor amounts of fat, such as the lungs or kidneys, without the need for an additional noncontrast scan. The virtual unenhanced application class is not recommended for the analysis of a potentially fatty liver. The Monoenergetic Plus application class simulates images that are scanned with an X-ray beam of a single energy level Kev. By changing the energy Kev, you can enhance the contrast between different materials. Monoenergetic Plus provides a range of Kev values from 40 to 190 Kev. Compared to the monoenergetic viewing mode, the MONOENERGETIC Plus application class provides images with less noise and parallel display of multiple monoenergetic plus regions of interest and their respective attenuation curves. Saving monoenergetic plus region of interest information for statistical evaluations is also available. Direct angio removes bone structures in CTA CT angiography scans to provide a bone free view of the vessel system. The prerequisite for bone removal is the decomposition of the material into its component parts, blood contrast agent and bone. There are two application classes for the bone removal. One is head bone removal. It is used to visualize head and geographies, including carotid scans. The other one is body bone removal. It is used to visualize the contrast agent in the body and extremities, for example for runoff CT angiography. Lung analysis combines 2 application subclasses, lung vessels and lung PBV perfused blood volume. Lung vessels visualizes the iodine enhancement in pulmonary vessels. Different colors are assigned to differentiate between perfused and non perfused pulmonary arteries. The iodine distribution within the lungs is displayed as color masks overlay in the result images. Lung PBV visualizes and quantifies the iodine uptake in the lung parenchyma. The lung PBV overlay image displays the iodine enhancement in the mixed image in Hounsfield units for the lung. During the preprocessing, the dual energy algorithms perform a material decomposition and extract the iodine enhancement. With the mixing ratio mini toolbar you can control the composition of the displayed images. The lung vessels overlay image enables you to differentiate between the high iodine and the low iodine concentrations in lung vessels. Compared to the lung vessels color masks on the lung PBV overlay images. The overlay information is displayed for all vessels and tissues in the image. The fused image is a combination of the mixed image and the lung vessels overlay image. The calculated overlay is displayed in red and cyan. Cyan areas indicate vessels with a high iodine concentration. The corresponding overlay Hounsfield unit values are positive. Red areas indicate vessels with a low iodine concentration. The corresponding overlay Hounsfield unit values are negative. The gout application class allows you to distinguish between your eight bone, bone marrow and contrast agent. Urate and contrast agent are highlighted with different colors. The overlay image supports you in distinguishing year eight bone and iodine from each other. Otential urate is displayed in green and iodine in purple by default. The Kidney Stones application class supports the therapeutic decision by clarifying what type of kidney stone your patient suffers from. Kidney stones consist of uric acid and calcium oxalate, and in a few cases, other material. Notice how the automatically preprocessed data shows the uric acid stones in red and any calcium compound in blue. Would you like to calculate the volume of a stone or the maximum and minimum diameter? Just activate the kidney stone marker from the upper right corner menu and click on the stone you want to evaluate. Notice that every stone is placed on the diagram for further comparison with the reference materials. Single CTDB bone marrow allows for the segmentation and the visualization of bone marrow based on a material decomposition into bone marrow and calcium. The color map shows the density of a virtual non calcium, that is an image of the bone marrow without any calcium. Therefore, higher densities, shown in green or yellow on this image could indicate various pathologies, such as bone bruises after trauma and diffuse tumor infiltrations. A side-by-side layout or a quantitative analysis can help you in the evaluation of such cases. In contrast, enhanced CT scans of the vessel system, the dual energy applications, direct angio and hard plaque display play a major role. It can be difficult to differentiate between calcified plaques and iodine contrast. Most radiologists assess the grade of a stenosis visually, manually adjusting the window level. Therefore, the results can vary significantly. The hard plaque display provides a color overlay to help you differentiate between a remaining vessel lumen and a calcified plaque at similar CT values. If you want to remove the plaques to simulate an angio view open the bone removal application. There the bone mask has been preprocessed and removed, and you can additionally hide. Or show the hard plaques. The brain hemorrhage application class allows you to distinguish contrast agent from a hemorrhage in the brain. This application class extracts contrast medium iodine from dual energy brain CT angio datasets. This provides an iodine distribution or enhancement map of the brain parenchyma. The application helps differentiate new blood within a resolving hemorrhagic site. You can change the mixing ratio of overlay image and content image by using the slider bar at the bottom of the segment. The heart EBV perfused blood volume application class allows you to visualize the contrast agent uptake in the myocardium. The isolation of the heart is part of the preprocessing. In cases involving material characterization of different tissues in the body, take a look at the rosy visualization. This application class provides an accurate material characterization based on its atomic properties, the atomic number and row, the electronic density. When you open this application, the preprocessed data set is displayed as a fusion of an atomic number image and an electronic density image. Place a region of interest you need in a quantitative evaluation of both parameters.
