About X-ray

While the field of imaging has grown dramatically over the years, X-rays are still the most common type of radiology exam. X-rays use external radiation to make clear pictures of bones, organs and other areas inside your body to help physicians diagnose and monitor health conditions.

How images are formed

X-rays pass through your body structures and onto specially treated plates (similar to camera film) or digital media, and a "negative" type picture is made. The more solid a structure is, the more white it appears on the film.

When you have an X-ray exam, different parts of your body allow varying amounts of the X-ray beams to pass through. The soft tissues in your body (such as blood, skin, fat and muscle) allow most of the X-ray to pass through and appear dark gray on the film or digital media.

A bone or a tumor, which is denser than the soft tissues, allows few of the X-rays to pass through and appears white on the X-ray film. At a break in a bone, the X-ray beam passes through the broken area and appears as a dark line within the white bone.

How X-rays are used

X-ray technology is used in many types of diagnostic procedures, such as arteriograms, computed tomography (CT) scans and fluoroscopy. Radiation during pregnancy may lead to birth defects. Always tell your radiologist or physician if you suspect you may be pregnant.
