We will review the normal anatomy of the thorax, particularly relating to pulmonary anatomy, with a review of the relationship of pulmonary vein, bronchus and artery and how this relates to understanding of lung patterns. We will also review ways in which thoracic artefacts or normal variant may mimic genuine pathology. We will also discuss the significant differentials for the lung patterns encountered and how the differentials may be narrowed down or ranked in accordance with their likelihood. We will also discuss appropriate further tests.
Key learning objectives:
1. Recognizing normal anatomy of the lung and identifying artefacts which can mimic pathology
2. Understanding how lung patterns are formed radiographically
3. Differential diagnoses for lung patterns and how to proceed with the case
