Mastering Chest X-Ray Projection: Optimizing Image Quality

A key determinant of chest X-ray quality is projection. A perfectly straight PA projection shows medial clavicle ends equidistant from the spinous process; rotation obscures anatomy and mimics pathology. In the AP projection, the heart and mediastinum appear magnified due to the…

• This educational piece outlines how to assess and correct projection errors on chest radiography, a fundamental call-prep skill.
• It details the anatomical landmarks used to judge rotation, including the medial ends of the clavicles and the thoracic spinous processes.
