Respiratory symptoms associated with a new lobe-based bronchial scoring system in an urban Chinese low-dose CT screening population.

ABSTRACT:

Objective

To develop a lobe-based bronchial scoring system in a general Chinese urban population undergoing low-dose CT (LDCT) screening and examining the association between the scores and the presence and absence of respiratory symptoms.

Materials and methods

A total of 989 Chinese participants aged 40-74 from the NELCIN-B3 study underwent LDCT screening. The scoring system assessed bronchiectasis by summing up CT findings in each of the five lung lobes, including severity and extent of bronchial dilatation and airway wall thickness, as well as the presence of mucoid impaction. The modified Reiff score was used as comparison. Multivariable logistic regression analyses were performed to examine the relationship between bronchial scores and respiratory symptoms.
