X-ray

Radiography

X-rays are a type of electromagnetic radiation, just like visible light.

An x-ray machine sends individual x-ray particles through the body. The images are recorded on a computer or film.

  • 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.
X-ray

X-rays are a form of ionizing radiation that can penetrate the body to form an image on film. Structures that are dense (such as bone) will appear white, air will be black, and other structures will be shades of gray depending on density. X-rays can provide information about obstructions, tumors, and other diseases, especially when coupled with the use of barium and air contrast within the bowel.
