Image Interpretation - Plain X-rays of the Adult Chest: Airspace Opacification

About this activity

This session will look at airspace disease. It will focus on practical aspects of identification of airspace pathology on chest radiographs, and consider the possible causes for the appearances. Radiographic case studies/examples will be used to demonstrate some of the important features. Objectives By the end of this session you will be able to: • Describe the lobar anatomy of the chest as demonstrated on frontal chest radiographs • Define the terms: consolidation, collapse, atelectasis and air bronchogram • Describe and localise pulmonary airspace disease using the 'silhouette sign' • Describe the common causes of airspace opacification • Discuss how the clinical presentation alters the likely diagnosis in patients with airspace disease
