X-ray is electromagnetic waves, a kind of radiation that can be used to take pictures of the inside of a person’s body. The images show the parts of your body in different shades of black and white. This is because different tissues absorb different amounts of radiation. Calcium in bones absorbs x-rays the most, so bones look white. Fat and other soft tissues absorb less and look gray. Air absorbs the least, so lungs look black.
What to Expect
Depending on the X-Ray exams requested, you may be asked to stand, sit, or lie down on an x-ray table. For many x-ray tests, you may be asked to wear an exam gown as well as a protective apron to minimize exposure to radiation. Bolsters or straps may be used to help you maintain the correct position for the x-ray. In all types of x-ray exams, you will be asked to hold very still in order to get the clearest image possible. The image-taking process is very quick; only a few seconds for each image. The duration of your visit will depend on the number of x-ray images taken.
Please inform your technologists if there is any chance you may be pregnant. In some cases of pregnancy, an alternative to x-ray may be recommended.
