Inspiratory and expiratory HRCT findings in Behçet's disease and correlation with pulmonary function tests

Quantification and optimisation of lung ventilation SPECT images

“…Furthermore, it has been concluded that the heterogeneous distribution of ventilation in asthma is an expression of the integrated system and not just the sum of independent responses of individual airways (Tgavalekos et al, 2007). Air trapping can be present even before pulmonary function tests are classified as abnormal or pulmonary symptoms become manifested (Ozer et al, 2005). Air trapping is for example due to aging, smoking and different obstructive diseases such as asthma (Ozer et al, 2005;Samee et al, 2003).…”

Air trapping is for example due to aging, smoking and different obstructive diseases such as asthma (Ozer et al, 2005;Samee et al, 2003). The severity of air trapping has been shown to increase with age and smoking (Lee et al, 2000).…”

“…Closure of the airways by air trapping occurs when the small airways, the bronchioles, collapse. According to Özer et al (Ozer et al, 2005), air trapping can be present even before lung function tests reveal abnormal results, or pulmonary symptoms become apparent. Possible causes of air trapping are aging, smoking and various obstructive diseases such as asthma (Ozer et al, 2005;Samee et al, 2003).…”

Evaluation of Biventricular Myocardial Performance Index in Patients with Behçet's Disease

“…16 -19 The prevalence of pulmonary manifestations in BD patients has been reported to be between 1.7% and 7.7%. 17 In a study by Ozer et al, 18 high-resolution computed tomography scans found that 70.6% of the patients with BD had grade 3 or 4 expiratory air trapping (indicating the presence of small airway disease), despite having normal pulmonary function tests. The study by Ozer et al 18 also demonstrated a variety of pulmonary parenchymal changes associated with BD, including transient focal or diffuse alveolar infiltrates and wedge-shaped opacities, reticular infiltrates and parenchymal hypovascular areas.…”
