Association between visual emphysema and lung nodules on low-dose CT scan in a Chinese Lung Cancer Screening Program (Nelcin-B3)

ConclusionIn a Chinese general population, visual emphysema based on LDCT is independently related to the presence of lung nodules ( ≥ 30 mm3) and specifically CLE subtype is related to positive Lung-RADS category. The risk of lung nodules increases with CLE severity.Key Points• Participants with emphysema had an increased risk of having lung nodules, especially smokers.• Participants with PSE were at a higher risk for lung nodules than those with CLE, but nodules in participants with CLE had a higher risk of positive Lung-RADS category.• The risk of lung nodules increases with CLE severity.
