Key facts about how to read chest X-rays Determining the view In this image, air is black, bones are white, and the rest of the tissues fall on a spectrum in between. This differential absorption allows for the creation of an image on radiographic film. Some of these rays are absorbed more than others depending on the tissues through which they travel. X-rays are emitted by a machine, travel through the patient, and are picked up by a receptor on the other side of the patient. ![]() It is almost always the first imaging study ordered to evaluate for pathologies of the thorax, although further diagnostic imaging, laboratory tests, and additional physical examinations may be necessary to help confirm the diagnosis.
