Emphysema: Imaging for Endoscopic Lung Volume Reduction.

Unlabelled: Chronic obstructive pulmonary disease (COPD) is characterized by two entities, the more airway-predominant type ("bronchitis") on the one hand, and emphysema-predominant type on the other. Imaging via high-resolution computed tomography plays an important role in phenotyping COPD. For patients with advanced lung emphysema, new endoscopic lung volume reduction therapies (ELVR) have been developed.

The Aging Lung: Clinical and Imaging Findings and the Fringe of Physiological State.

Unlabelled: Since aspects of demographic transition have become an essential part of socioeconomic, medical and health-care research in the last decades, it is vital for the radiologist to discriminate between normal ageing related effects and abnormal imaging findings in the elderly. This article reviews functional and structural aspects of the ageing lung and focuses on typical ageing related radiological patterns.

Key Points: • The physiological aging process of the thoracic organs shows typical structural and functional aspects.
