What Is An X-Ray?
X-rays are a form of electromagnetic radiation, like visible light, that are used to see internal structures in the body. The rays are reflected onto film. Dense structures, like bone, block most of the radiation and appear white on film, while muscle and tissues reflect less and appear gray. This is the technology behind radiology, mammography, and computed tomography (CT) scans.
How Is An X-Ray Performed?
X-rays are performed with a patient standing or lying in front of an x-ray machine. There is no discomfort, but you might be asked to hold still for very brief periods of time.
How Do I Prepare For An X-Ray?
You will be asked to remove all jewelry and wear a hospital gown, because clothes and metal can obscure images. Inform the technician before the test if you are pregnant, might be pregnant or have an Intra-Uterine Device (IUD) inserted.
