Similar Patient Search (CT Lung Assistant)

The similar patient search web service is an interactive tool that provides supplementary information to a radiologist reading chest CT images. It presents visually similar reference cases with known diagnosis from a cloud database, and in addition, relevant textbook content from the medical publisher team A. Please keep in mind that the similar patient search web service is updated with new features frequently. Therefore, your user interface might differ slightly from what is shown in this video. Please also note that the actual usage of the tool might differ slightly on the different host systems. For example, in single via or single carbon space without changing the intended purpose of the tool. The tool functionality defined in this video is applicable to any of the Siemens healthineers products in which you find this tool. The CT Lung assistant tool which calls U the web service is available in the M reading workflow. You need to have an Internet connection on the single via client to be able to use this feature. To perform a new search in the similar patient search web service, select the tool contact Lung assistant in the tools gallery. You can add this to your favorite tools by drag and drop. After you activate the tool, you can draw a region of interest in the axial view of the lung series. It is recommended that you delineate this region of interest in a series using a long kernel and in a region that includes the most characteristic pathological pattern. The similar patient search web services page opens automatically after the region of interest has been drawn. The algorithm searches the patch you have delineated against the cases available in the database. The results represent the database items that are most similar to the patch that you have delineated. To know which diseases are included in the database of this application, please hover the mouse over the help icon and select cover diseases. The results of the search can be rearranged by applying clinical filter tags. You can either prioritize diseases with certain clinical characteristics by clicking the tags once, or filter those diseases out by clicking a second time. Diseases which are filtered out can be found at the end of the list. Click a third time to deactivate A tag. On the left pane, all the patches you delineated are displayed and you can start a combined search. In this case, the numbers in the retrieved reference images indicate which of your patches resulted in the reference image being selected. Click on the disease name or on a thumbnail and you are directed to the detailed view. In this detailed view, you can click on each of the thumbnails to see the corresponding full slice. Below the textbook content from TIMET Eref is provided, which includes, amongst others, the definition, imaging signs and clinical aspects of the selected disease. You can click on the icons on the right and you are directed to the corresponding content on the tmet eref page. To see the full external content, you are required to have a subscription with the publisher. You can also search for a specific disease using the search button. Click on the home icon to return to the search results page. If you want to try, you can access the digital marketplace by clicking on the shopping cart. Here you can search for an request, a quote or immediately activate a 90 day trial of the product.

Pneumocystis Jirovecii Pneumonia ... COVID-19 Etiology and Pathogenesis Viral infections caused by Corona virus ( Severe Acute Respiratory Syndrome-Coronavirus-2, SARS-CoV-2) · COVID-19 ( Coronavirus-Disease-2019) was first described in late 2019 in Wuhan, China and spread worldwide as a pandemic in 2020. Although it primarily involves the airways, the virus may also affect other organs such the heart, liver, kidneys and CNS. . Diffuse alveolar damage is seen histologically, with an organising pneumonia also being seen later in the course of the disease. The prognosis is highly variable, ranging from asymptomatic infections to severe pneumonia with sepsis, organ failure and death. Elderly patients and those with underlying health conditions have a significantly poorer prognosis with high mortality. Children and young adults rarely develop severe forms of this disease. May be normal. Indistinct, faint opacities at the periphery of the lung. Ground-glass opacities and rarely consolidation, predominantly at the periphery of the lung. . Lung fibrosis may occur later in the course of the disease. . Symtoms of a flu-like infection, especially with fever, dry cough and aching limbs . Loss of sensations of smell and taste, common cold, diarrhea. Pneumonia and respiratory failure. . Severity of clinical manifestations varies greatly, ranging from asymptomatic to severe disease requiring mechanical ventilation and possibly even death. . Confirmation of the suspected diagnosis in order to decide whether patient isolation is necessary. Evidence of complications such as ARDS, bacterial superinfection, pulmonary embolism. Pneumonia . (Viral)pneumonias due to other pathogens give rise to similar changes in the lungs but peripheral ground-glass infiltrates are more commonly seen in COVID-19 pneumonia. ARDS . It may not be possible to conclusively differentiate between changes due to COVID-19 pneumonia and ARDS or a combination of the two especially in severely ill patients. Ground-glass infiltrates in a predominantly peripheral distribution favor a diagnosis of COVID pneumonia. . A negative throat swab does not necessarily rule out COVID-19 pneumonia, since this may be false negative, if, for instance, the swab was delayed. An antibody test or bronchioalveolar lavage may be performed, if necessary. Bernheim A, Mei X, Huang M, Yang Y, Fayad ZA, Zhang N, Diao K, Lin B, Zhu X, Li K, Li S, Shan H, Jacobi A, Chung M.
