Microscopic and macroscopic measurements of emphysema: relation to carbon monoxide gas transfer.
BACKGROUND Studies of the relation between the severity of structural change in emphysema and physiological abnormality have been based on macroscopic assessments, which have not been truly quantitative or sensitive enough to detect early changes. With a highly reproducible method for measuring emphysema using histological sections and a semiautomatic image analysis system, this quantitative as...
متن کاملComputed Tomography Measurement of Rib Cage Morphometry in Emphysema
BACKGROUND Factors determining the shape of the human rib cage are not completely understood. We aimed to quantify the contribution of anthropometric and COPD-related changes to rib cage variability in adult cigarette smokers. METHODS Rib cage diameters and areas (calculated from the inner surface of the rib cage) in 816 smokers with or without COPD, were evaluated at three anatomical levels ...
متن کاملA case of endobronchial polyp mimicking congenital lobar emphysema in an infant

It results from cartilage deficiency and bronchomalacia causing distal air trapping and respiratory distress.

متن کاملVentilation heterogeneity in ex-smokers without airflow limitation.
RATIONALE AND OBJECTIVES Hyperpolarized (3)He magnetic resonance imaging (MRI) ventilation abnormalities are visible in ex-smokers without airflow limitation, but the clinical relevance of this is not well-understood. Our objective was to phenotype healthy ex-smokers with normal and abnormally elevated ventilation defect percent (VDP). MATERIALS AND METHODS Sixty ex-smokers without airflow li...
