X-Ray Imaging: Anatomy of the Skeleton
An X-ray (radiograph) is a non-invasive and painless medical test that helps physicians diagnose and treat medical conditions. X-ray imaging produces pictures of the inside of the body. X-rays are a type of energy called electromagnetic radiation. X-rays pass through body tissues onto specially designed film or a digital detector. This technology makes it possible to view the anatomy of the skeleton.
Preparation for an X-Ray of the Skeleton
Before the procedure, the patient should tell the health care practitioner about any medications they may be taking or any medical conditions they have. It's important to remove all metal items, such as jewelry, to prevent incorrect images. In addition, the patient may be asked to change into a gown for the examination.
Procedure for an X-Ray of the Skeleton
During the procedure, an x-ray technician will place the patient on the x-ray table and the extremity or body part being examined will be placed in a specific position. The x-ray machine will then be lined up to the part of the body being x-rayed, and the patient will be protected by a lead apron during the procedure. The x-ray technician will step behind a protective wall while the image is taken.
Types of X-Ray Imaging of the Skeleton
The most common type of x-ray imaging used for the skeleton is called a plain film x-ray. The parts of the body that can be x-rayed include the feet, hands, spine, arms, chest, and any joint. In some cases, a special x-ray may be necessary, such as a bone scan or a computed tomography (CT) scan.
Risks of X-Ray Imaging of the Skeleton
X-ray imaging is one of the safest medical tests. There is a very small amount of radiation exposure during an x-ray, and the benefits of the x-ray usually outweigh the risks. However, pregnant women should inform their health care practitioner if they are pregnant, as radiation exposure during the test can be risky for the unborn baby.
Why an X-Ray of the Skeleton is Performed
X-ray imaging is most commonly used to diagnose bone conditions, such as fractures, arthritis, and other bone diseases. It can also be used to diagnose tumors or infections, to measure bone length, and to evaluate joint space narrowing. When combined with an MRI, x-rays can also help diagnose soft tissue and joint injuries.
When an X-Ray of the Skeleton is Performed
X-ray imaging can be performed at any time a health care practitioner suspects or is concerned about a bone condition or injury. It can also be used to monitor healing after a fracture or surgery, to detect bone loss from arthritis, and to assess bone infection. An x-ray can also be used to help guide injections to a specific area of the body.
