Effect of Zafirlukast on improving lung function in patients with chronic obstructive pulmonary diseases
Background : There is little evidence about the role of Zafirlukast (a highly selective LTD4 antagonist) in Chronic Obstructive Pulmonary Disease (COPD). The Zafirlukast can reduce the need for short-acting rescue β2 agonists, produce fewer exacerbations of asthma and increased quality of life as possible benefits treatment for asthma. The aim of our study was to evaluate the effects of Zafir...
متن کاملCorrelation of 68Ga Ventilation-Perfusion PET/CT with Pulmonary Function Test Indices for Assessing Lung Function.
UNLABELLED Pulmonary function tests (PFTs) are routinely used to assess lung function, but they do not provide information about regional pulmonary dysfunction. We aimed to assess correlation of quantitative ventilation-perfusion (V/Q) PET/CT with PFT indices. METHODS Thirty patients underwent V/Q PET/CT and PFT. Respiration-gated images were acquired after inhalation of (68)Ga-carbon nanopar...
متن کاملCT-Pathology Correlation in Diffuse Pulmonary Diseases
1. Centrilobular diseases (1) Pulmonary emphysema Early centrilobular emphysema starts from the proximal portion of the pulmonary acinus where respiratory bronchioles and neighboring alveoli are distributed. Typical CT findings are low-attenuation areas (LAA) surrounded by perilobular normal lung. Such LAA lacks a distinct wall. Pulmonary arteries within LAA are isolated and narrowed. The disea...
متن کاملQuantitative assessment of Pulmonary Alveolar Proteinosis (PAP) with ultra-dose CT and correlation with Pulmonary Function Tests (PFTs)
BACKGROUND The purpose of this study was to investigate whether ultra-low-dose chest computed tomography (CT) can be used for visual assessment of CT features in patients with pulmonary alveolar proteinosis (PAP) and to evaluate the relationship between the quantitative analysis of the ultra-low-dose CT scans and the pulmonary function tests (PFTs). METHODS Thirty-eight patients (mean [SD] ag...
متن کاملEmphysema in asymptomatic smokers: quantitative CT evaluation in correlation with pulmonary function tests.
PURPOSE To provide quantitative information on emphysema in asymptomatic smokers in correlation with pulmonary function tests (PFT). PATIENTS AND METHODS The study population included 75 smokers (current smokers: n=39; ex-smokers: n=36) and 25 nonsmokers who underwent volumetric high-resolution CT of the chest with automated quantification of emphysema and PFTs. RESULTS Current smokers had ...
