In medicine, a chest radiograph, commonly called a chest x-ray (CXR), is a projection radiograph of the chest used to diagnose conditions affecting the chest, its contents, and nearby structures. Chest radiographs are among the most common films taken, being diagnostic of many conditions. Like all methods of radiography, chest radiography employs ionizing radiation in the form of x-rays to generate images of the chest. The typical radiation dose to an adult from a chest radiograph is around 0.06 mSv.
