Purpose Assessment the state of the lungs using CT in the dynamic follow-up of pa-tients who have suffered from viral COVID-19 pneumonia in the delayed period af-ter 6-10 months, and to identify the relationship of residual lung changes with the clinical condition and results of external respiratory function (ERF) Materials and methods We examined 78 patients who had suffered from bilateral polysegmental viral COVID-19 pneumonia in April-May 2020, using multi-spiral computed tomography (CT) of the lungs All patients had a medical history, performed CT scans of the lungs in the acute and delayed (6-10 months after hospitalization) phases, and a study of FVD in the delayed phase The analysis of a series of tomograms of the lungs in dynamics was carried out We developed an severity score of the lung condition (LungSS), expressed in the total score, which was calculated based on the score of typical patterns characteristic of viral Covid19-pneumonia, as well as residual changes and areas of fibrosis LungSS was calculated for each patient in the acute and delayed follow-up periods Results The present study shows the dynamics of lung changes in the delayed peri-od 6-10 months after the viral Covid19-pneumonia Residual lung changes were detected in 66 people (84,6%) Of these, 35,9% of patients have areas of fibrosis, but most of the residu-al changes are linear and small-nodular seals (76,9%) The frequency of detection of residual reticular changes and consolidation was low (15,3%, 1,3%, respectively) Attention is drawn to the relatively frequent detection of areas of "Ground-glass opacity "(10,8%) In patients with severe and critical course of viral Covid19-pneumonia (CT3 and CT4), LungSS in the delayed follow-up period did not significantly differ from that in patients with mild and mod-erate course (CT1 and CT2) of the disease (4,5 [0,22], 2,5 [0,16], accordingly, p=0,61) There was no significant correlation between the detected residual lung changes in the delayed period and ERF Conclusion In a significant part of patients (84,6%) who have suffered from COVID-19 viral pneumonia, residual changes in the lung parenchyma persist, mainly in the form of linear seals and to a lesser extent fibrosis These changes did not have a reliable relation-ship with the results of the FVD LungSS proposed in this study reflects the dynamic picture of lung changes in the acute and delayed period, and can be a good indicator for monitoring patients who have suffered from COVID-19 viral pneumonia.

Ct Scans sentence examples within chest computed tomography
Here, we use multi-type feature fusion and selection to predict COVID-19 infections on chest computed tomography (CT) scans The scheme operates in four steps Initially, we prepared a database containing COVID-19 pneumonia and normal CT scans These images were retrieved from the Radiopaedia COVID-19 website The images were divided into training and test sets in a ratio of 70:30 Then, multiple features were extracted from the training data We used canonical correlation analysis to fuse the features into single vectors;this enhanced the predictive capacity We next implemented a genetic algorithm (GA) in which an Extreme Learning Machine (ELM) served to assess GA fitness Based on the ELM losses, the most discriminatory features were selected and saved as an ELM Model Test images were sent to the model, and the best-selected features compared to those of the trained model to allow final predictions Validation employed the collected chest CT scans The best predictive accuracy of the ELM classifier was 93 9%;the scheme was effective.
