3-chest-x-rayChest X-Ray is a projection radiograph of the chest used to visualize upper body cavity anatomy to identify conditions affecting the chest, its contents, and nearby structures. Like all methods of radiography, chest X-Ray employs ionizing radiation in the form of X-rays to generate images. The mean radiation dose to an adult from a chest radiograph is around 0.02 mSv (2 mrem) for a front view (PA or posterior-anterior) and 0.08 mSv (8 mrem) for a side view (LL or latero-lateral).
