Abstract. This article provides a historical overview of the use of radionuclide methods for the diagnosis of HIV infection and its complications. Molecular imaging methods have been effectively used for a long period of time for the qualitative and quantitative assessment of lymphadenopathy and for the study of the biodistribution of a radiopharmaceutical, on the basis of which it is possible to indirectly track the dynamics of the patient's condition. Also, radionuclide diagnostic methods, in particular PET / CT, can detect malignant neoplasms, which are a frequent complication of HIV infection in the late stages. The works devoted to the determination of the possibilities of nuclear medicine in the diagnosis of HIV have had a significant impact on the development of modern radiation diagnostics of infectious diseases.
Annotation: This article presents the results of evaluating the measurement of the area of titanium mesh implants using computed tomography (CT) data based on the use of an experimental model. Hernioplasty using mesh implants is a modern method of treating hernias of the anterior abdominal wall. The most common complication of hernia surgery is hernia recurrence. The main reason for the development of recurrence is the discrepancy between the size of the implant and the hernial defect, which may occur due to a decrease in the size of the mesh after its installation. CT can be used to assess changes in mesh size. The study showed that the dimensions obtained because of non-invasive measurement of the mesh implant by CT did not significantly differ from the dimensions of the implant obtained intraoperatively. Thus, CT is a highly effective method for assessing the size of titanium mesh implants and can be used in clinical practice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
