The aim of this study was to analyze initial chest computed tomography CT findings in COVID pneumonia and identify features associated with poor prognosis.
Purpose: With the help of quantitative computed tomography QCTit is possible to identify smoking-associated airway remodeling. However, there is currently little information on whether QCT-based airway metrics are sensitive to early airway wall remodeling in subclinical phases of smoking-associated airway disease.
This study aimed to evaluate a predictive model that normalized airway parameters and investigate structural airway alterations in smokers with normal-looking CT using the normalization scheme. Methods: In this retrospective analysis, non-smokers male 97, female and 69 smokers male 66, female 3 from January to December were included, and airway parameters were quantitatively analyzed.
To control inter-subject variability, multiple linear regressions of tracheal wall thickness WTdiameter Dand luminal area LA were performed, adjusted for age, sex, and height. Using this normalization scheme, airway parameters with matched generation were compared between smokers and non-smokers. : Using the normalization scheme, it was possible to assess generation-based structural alterations of the airways in subclinical smokers.
Conclusion: QCT assessment for subclinical smokers can help identify minimal structural changes in airways induced by smoking.
