X-rays use waves of electromagnetic radiation to form images of organs and other structures inside the body. They are absorbed in differing amounts by different body tissues. Skin, fat, and muscle allow more x-rays to pass through, but bones are denser and absorb x-rays. The ultimate result is a shadow on a film that shows images of bones as white, and softer tissues as shades of gray.
Plain x-rays take less than a minute.
How X-Rays Work
In diagnosing inflammatory bowel disease, x-rays are usually not done alone. However, x-rays are done as a part of longer procedures such as a barium enema or an upper GI series. X-rays also may be used if a bowel obstruction or toxic megacolon is suspected. With these conditions, passing barium through the GI tract to do a contrast x-ray may not be possible.
Other x rays: MCU, RGU, IVP, BARIUM SERIES, SINOGRAMS, FISTULOGRAMS etc.
