X-ray

What is X-ray?
X-rays are a form of electromagnetic radiation, just like visible light. In a health care setting, a machines sends are individual x-ray particles, called photons. These particles pass through the body. A computer is used to record the images that are created.

Structures that are dense (such as bone) will block most of the x-ray particles, and will appear white. Metal and contrast media (special dye used to highlight areas of the body) will also appear white. Structures containing air will be black and muscle, fat, and fluid will appear as shades of gray.

Much like conventional photography, motion causes blurry images on radiographs, and thus, patients may be asked to hold their breath or not move during the brief exposure (about 1 second).

How to prepare for the test
Inform the health care provider prior to the exam if you are pregnant, may be pregnant, or have an IUD inserted.

You will remove all jewelry and wear a hospital gown during the x-ray examination because metal and certain clothing can obscure the images and require repeat studies.

How the test will feel
There is no discomfort from x-ray exposure. Patients may be asked to stay still in awkward positions for a short period of time.
