How the Test is Performed
The test is done in a hospital radiology department or in your health care provider's office by an x射线 technologist.
You will lie on a table or stand in front of the x射线 machine, depending on the bone that is injured. You may be asked to change position so that different x射线 views can be taken.
The x射线s pass through your body. A computer or special film records the images.
Structures that are dense (such as bone) will block most of the x射线 particles. These areas 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. Muscle, fat, and fluid will appear as shades of gray.
How to Prepare for the Test
Tell your provider if you are pregnant. You must remove all jewelry before the x射线.
How the Test will Feel
The x射线s are painless. Changing positions and moving the injured area for different x射线 views may be uncomfortable. If the whole skeleton is being imaged, the test most often takes 1 hour or more.
Why the Test is Performed
This test is used to look for:
- 骨折 or broken bone
- Cancer that has spread to other areas of the body
骨髓炎 (inflammation of the bone caused by an infection)- Bone damage due to trauma (such as an auto accident) or degenerative conditions
- Abnormalities in the soft tissue around the bone
What Abnormal Results Mean
Abnormal findings include:
- 骨折
骨肿瘤 - Degenerative bone conditions
骨髓炎
风险
There is low radiation exposure. X-rays machines are set to provide the smallest amount of radiation exposure needed to produce the image. Most experts feel that the risk is low compared with the benefits.
Children and the fetuses of pregnant women are more sensitive to the risks of the x射线. A protective shield may be worn over areas not being scanned.
