Assessment of High-resolution Computed Tomography Thorax Volumetric Indices in Covid-19 Patients and Correlation with Biochemical Markers

Materials and Methods: This is a hospital-based Cross-sectional study, with a follow-up among 100 Hospitalized clinically moderate to severe Covid19 patients who recovered after four months. [...]the different CT indices (NL, NL%) can be used along with Biochemical parameters (CRP and d-Dimer) for structural and functional recovery in Covid-19 patients. [...]it's still essential to review radiological results after a patient leaves the hospital and while they' re recovering.61 Activation of endothelial cells and macrophages, inhibition of neutrophil apoptosis and expression of endothelial NO synthase, platelet aggregation, accumulation of lipid and thrombosis, complement activation, fibrosis, and upregulation of proinflammatory cytokine expression are all pathophysiological stages of acute or chronic inflammatory diseases.71 There is a significant prevalence of both macrovascular and microvascular thrombotic events in Covid-19 cases. Materials and Methods The hospital-basedcross-sectional study enrolled 100 post covid recovered patients with clinically moderate to severe infection during hospitalization and CT scores of more than 8/25. Results The hospital-based cross-sectional study enrolled 100 cases of post-Covid recovered patients with clinically moderate to severe infection during hospitalization.The mean age (years) among the subjects was 48.56 ± 13.87 years ranging from 24 to 80 years. The WL (L) correlations with Biochemical parameters were not statistically significant during Covid.NL% has a negative correlation with d-Dimer with a correlation coefficient of -0.25. d-Dimer decreases by -0.01 times for each unit increase in NL% (Table 2).
