Evaluation of airway wall thickness and air trapping by HRCT in asymptomatic asthma.
The aim of this study was to examine the relationship between the structural changes in large and small airways in asymptomatic asthmatics quantified by high-resolution computed tomography (HRCT) and airflow obstruction. The bronchial wall thickness at the trunk of the apical bronchus (B1) of the right upper lobe was used for assessment of the large airways. Air trapping, evaluated by the ratio...
متن کاملAirway wall thickness on HRCT scans decreases with age and increases with smoking
BACKGROUND To investigate if age, gender and smoking are associated with airway wall thickness (AWT) measured by high resolution computed tomography (HRCT) and if higher AWT is associated with lower levels of pulmonary function in healthy current- and never-smokers with a wide age range. METHODS HRCT scans were performed in 99 subjects (48 never- and 51 current-smokers, median age 39 years [I...
متن کاملEvaluation of airway wall thickness via high-resolution computed tomography in mild intermittent asthma.
INTRODUCTION This study aims to evaluate bronchial thickness via thorax high-resolution computed tomography (HRCT) in subjects with mild intermittent asthma in comparison with healthy control subjects. METHODS A total of 37 out-patients (mean ± SD age = 36.7 years (9.7 years); 54.8% males) with mild intermittent asthma and 13 healthy control subjects (mean ± SD age = 25.0 years (2.9 years); 6...
متن کاملHigh-resolution CT findings in patients with near-fatal asthma: comparison of patients with mild-to-severe asthma and normal control subjects and changes in airway abnormalities following steroid treatment.
STUDY OBJECTIVES Extensive airway inflammation and excessive mucus production are implicated in deaths from asthma. High-resolution CT (HRCT) can be used to image both large and small airway abnormalities in asthmatics. The aims of this study were to clarify the distinction of HRCT features between near-fatal asthma (NFA) and non-NFA, and to evaluate serial follow-up HRCT scans of patients with...
