Imaging in Asthma
http://emedicine.medscape.com/article/353436-overview Peter G Canaday, MD ; Jannette Collins, MD, MEd, FCCP Asthma is a common disorder that primarily involves the airways. Traditionally, asthma has been considered a disorder of airway smooth muscle mediators and anatomic elements of the airway mucosa. Although the causes of asthma are separated into allergic and nonallergic ones, considerable crossover is […]

Correlation of Aging and Smoking with Air Trapping at Thin-Section CT
PURPOSE: To assess the frequency and degree of air trapping at thin-section computed tomography (CT) of the lung in relation to age and smoking history in asymptomatic subjects. MATERIALS AND METHODS: Thin-section CT of the lung was performed prospectively at end inspiration and end expiration in 82 subjects (27 smokers, 55 nonsmokers) without any history […]
CT of Emphysema
http://www.radiologic.theclinics.com/article/PIIS0033838903001076/abstract John D. Newell Jr, MD This article focuses on three main topics: (1) the importance of emphysema as a serious respiratory disease, (2) qualitative assessment of emphysema using CT, and (3) the emerging importance of quantitative CT in the evaluation of patients with emphysema for surgery and drug therapy. CT also can identify the […]
