Abdominal Radiography Radiology |
|
Abdominal X-rays are one of the most commonly taken X-ray images used in hospitals and clinics today.
An abdominal X-ray is taken when a patient is suspected of having problems with his digestive organs, hepatobiliary and urinary systems, or other abdominal structures.
When an abdominal X-ray is taken, radiation is momentarily applied to the abdomen. The image that is produced is the result of passing X-rays through the abdomen, to the film. Structures like bone or calcification, which are dense and have a high atomic number, absorb a lot of radiation, so that fewer X-rays reach the film, and appear white. Structures like bowel gas, which are full of air and have a low atomic number and density, appear black because most X-rays pass through without being absorbed. Liver, fat, tumor, and fluid absorb less X-rays than bone, but absorb more than air, and consequently appear gray on the film.
