Pulmonary hypertension associated with chronic obstructive pulmonary disease
Pulmonary hypertension associated with chronic obstructive pulmonary disease (PH-COPD) can be a common complication of chronic obstructive pulmonary disease and usually manifests as mild to moderate pulmonary hypertension in those with advanced COPD. Pulmonary arterial pressures in this situatio...
Article
Chronic obstructive pulmonary disease
Chronic obstructive pulmonary disease (COPD) represents a spectrum of obstructive airway diseases. It includes two key components which are chronic bronchitis-small airways disease and emphysema.
Epidemiology
The most common cause has historically been (and unfortunately continues to be) ciga...
Article
Confluent centrilobular emphysema
Confluent centrilobular emphysema is one of the proposed subtypes of classifying emphysema (primarily centrilobular emphysema). It is considered the second most severe from (although not as severe as advanced destructive emphysema) and characterized by coalescent centrilobular or lobular lucenci...
Article
Advanced destructive emphysema
Advanced destructive emphysema (ADE) is one of the proposed subtypes of classifying emphysema (primarily centrilobular emphysema). It is considered the most severe from and is panlobular radiolucencies characterized by hyperexpansion of secondary pulmonary lobules and distortion of pulmonary arc...

Article
Dynamic tracheal collapse
Dynamic tracheal collapse refers to collapse of the trachea during expiration. It is perhaps best assessed on CT in the end expiratory phase. An inspiratory series is also useful for comparative purposes. The term excessive dynamic airway collapse (EDAC) refers to abnormal and exaggerated bulgin...
Article
Chest (expiratory view)
An expiratory chest radiograph can be taken in either a PA or AP projection, and can also be taken with a mobile/portable unit.
Chest radiographs may inadvertently be acquired in expiration (instead of inspiration), and this will affect interpretation with the cardiac silhouette appearing enla...

Psoriasis (pulmonary manifestations)
Pulmonary manifestations of psoriasis is uncommon and only thought to represent a small percentage of patients. They can include:
interstitial lung disease 1
only thought to affect around 2% of patients with psoriasis
may be seen as ground-glass and/or irregular linear (reticular) opacities i...
Article
Tracheal diverticulum
Tracheal diverticula, also known as tracheoceles, are usually an incidental finding. Occasionally they may mimic pneumomediastinum, a so-called pseudopneumomediastinum.
Terminology
There is an overlap in the use and description of the terms paratracheal air cyst and a tracheal diverticulum in ...
Article
Paratracheal air cyst
Paratracheal air cysts are not an uncommon incidental finding in routine thoracic imaging. They characteristically occur on the right side, in the region of the thoracic inlet. Occasionally they may mimic pneumomediastinum, so-called pseudopneumomediastinum.
Terminology
Paratracheal air cysts ...
Article
Accessory muscles of respiration
Accessory muscles of respiration refer to muscles that provide assistance to the main breathing muscles, mainly when additional power is needed, for example during exercise or those with airway pathologies (e.g. COPD) 1,2.
During normal quiet breathing, inspiration is an active process primaril...
