Introduction to Chest X-Ray Interpretation

Abstract

A chest radiograph—or chest X-ray (CXR)—is the most commonly requested first-line examination for the diagnosis of numerous clinical scenarios thanks to the widespread availability, low radiation doses, and modest costs. CXRs are optimal to confirm clinical suspicions based on specific signs and symptoms; however, without a proper diagnostic suspicion beforehand, its accuracy drops drastically. CXRs also play a decisive role in the intensive care unit, being fundamental for a quick assessment of patient conditions and to verify the correct placement of intensive-care devices (venous catheters, cannulas for ventilation, etc.).
