Summary: This study evaluated the anatomical and volumetric predictability of CBCT-based VPP software for SPECT/CT imaging results in HCC patients undergoing TARE. The results showed that the CBCT-based VPP software accurately and reliably predicted the anatomical and volumetric results of Tc-99m-MAA SPECT/CT in HCC patients during TARE.

Summary: The study evaluated the effectiveness of different filters in improving the quality of myocardial perfusion single-photon emission computed tomography (SPECT) images. Data from 30 patients, consisting of over 900 images, were collected using the Siemens Symbia T2 dual-head SPECT/CT scanner. The results showed that the Wiener filter with a kernel size of 5 x 5 outperformed other filters in denoising the SPECT images.

Summary: This study evaluated the prognostic value of SPECT/CT imaging of foot perfusion in predicting amputation outcomes in patients with critical limb ischemia and diabetes mellitus. The results showed that patients with lower microvascular perfusion response were more likely to undergo amputation, with high-perfusion responders having lower risk of amputation after revascularization.

Summary: Bipolar disorder is a common mental illness that often experiences a delayed diagnosis, which can lead to severe consequences. Brain perfusion SPECT neuroimaging can reveal visual correlates of brain function and potentially predict an individual's risk for developing symptomatic bipolar disorder.

Summary: Coronary artery disease is a major global health concern with noninvasive imaging tests playing a crucial role in its diagnosis and management. Myocardial perfusion imaging, along with other noninvasive tests such as stress echocardiography, coronary computed tomography angiography, and cardiac magnetic resonance imaging, have been widely used for evaluating ischemia and myocardial viability. The accuracy and clinical significance of these tests are essential in guiding risk stratification and revascularization decisions.

Summary: This study examined whether the ionizing radiation dose from a CT head scan at the age of 6-16 years affects academic performance and high school eligibility. The results showed no statistically significant differences between the exposed and unexposed participants in any of the variables studied.

Summary: The study evaluated the feasibility of myocardial perfusion ratio (MPR) in static computed tomography perfusion (CTP) for detecting myocardial perfusion abnormalities. The results showed that MPR had higher diagnostic accuracy for detecting myocardial perfusion abnormalities compared to other quantitative parameters.

Summary: The purpose of this study was to determine if the image acquisition time for the salivagram can be shortened without significantly reducing the sensitivity in detecting aspiration. It was found that evidence of aspiration could be detected within the first 40 minutes of dynamic imaging, therefore the originally described 60-minute protocol can be safely shortened to 40 or even 30 minutes.

Summary: Coronary artery disease is a common cardiovascular disease that can be assessed using various functional tests. These tests provide detailed imaging information to better evaluate the condition of patients. Cardiovascular imaging techniques have greatly contributed to our understanding of the physiological and clinical implications of CAD.

Summary: Radionuclide imaging is a premier imaging method in clinical practice, utilizing PET and SPECT to detect anatomical abnormalities. Peptides as targeting vectors for contrast agents offer high specificity and low toxicity. Radiolabeled peptide probes have become essential tools for clinical radionuclide diagnosis.

Summary: Climate change has led to an increase in wildfires, resulting in longer and larger fire seasons. The study assessed the air pollution and health risks caused by smoke exposure during fire season, with findings showing significant increases in pollutant concentrations during wildfire periods, with higher health risks in industrial centers similar to Bratsk.

Summary: The latest forecasts indicate wildfire activity in many parts of the world, posing health risks to the population. Lack of digital decision-making systems makes it difficult to predict the impact and provide timely medical care. This study assesses health risks associated with sub-daily exposure to wildfire smoke near populated areas. The frequency of additional medical care requests ranged from 0.137 to 0.933 per 1000 population during the fire period in settlements with risk levels >0.01.

Summary: Monitoring and analyzing data on environmental pollution during forest fires and their health impacts in different geographical areas is crucial for determining adverse health effects and identifying vulnerable population groups. A service-oriented geoportal system is being developed to assess the impact of air quality on public health. Specialized original services have been created to allow users to operate the file system on the server through their browsers.
