PURPOSE: Using low dose CT scan and quantitative analysis to evaluate airway remodeling and air trapping in asthmatic patients, discuss and define CT phenotype of asthma.
METHODS: 52 stable asthmatic patients, included 29 cases of severe asthma, 23 cases of non-severe asthma, and 20 cases of healthy control subjects were studied, with completed clinical data, paired inspiratory and respiratory phase CT scan and quantitative analysis of CT images. The factor and cluster analysis of quantitative CT index were used to analyze CT phenotypes of asthmatic patients, and their clinical features were studied by differences in statistics analysis of the clinical index of the 3 different CT phenotypes.
