Qualitative and Quantitative Assessment of Emphysema Using Dark-Field Chest Radiography.

Radiology, 2022
Background Dark-field chest radiography allows for assessment of lung alveolar structure by exploiting wave optical properties of x-rays. Purpose To evaluate the qualitative and quantitative features of dark-field chest radiography in participants with ...

A vision transformer for emphysema classification using CT images

Physics in Medicine and Biology, 2021
Objective. Emphysema is characterized by the destruction and permanent enlargement of the alveoli in the lung. According to visual CT appearance, emphysema can be divided into three subtypes: centrilobular emphysema (CLE), panlobular emphysema (PLE), and

EMPHYSEMA

Archives of Dermatology, 1970
AbstractThis review of the medical literature on emphysema before and during the nineteenth century clearly demonstrates that the disease was highly prevalent before modern times. The alleged increase in the prevalence of emphysema during recent decades—on the basis of official death certifications—is a statistical illusion.

Endobronchial Valve Therapy in Patients with Homogeneous Emphysema. Results from the IMPACT Study.

American Journal of Respiratory and Critical Care Medicine, 2016
RATIONALE Endobronchial valves (EBVs) have been successfully used in patients with severe heterogeneous emphysema to improve lung physiology. Limited available data suggest that EBVs are also effective in homogeneous emphysema.

Pathophysiology of Emphysema

Clinics in Chest Medicine, 1983
The pathophysiology of emphysema is best explained on the basis of decreased pulmonary elastic recoil. At any pleural pressure, the lung volume is higher than normal. Additionally, the altered relation between pleural and alveolar pressure facilitates expiratory dynamic compression of airways.

Requirement for macrophage elastase for cigarette smoke-induced emphysema in mice.

Science, 1997
To determine which proteinases are responsible for the lung destruction characteristic of pulmonary emphysema, macrophage elastase-deficient (MME-/-) mice were subjected to cigarette smoke.
