A pelvis x-ray is a picture of the bones around both the hips. The pelvis connects the legs to the body.
X-ray - pelvis
How the Test is Performed
The test is done in a radiology department or in the health care provider's office by an x-ray technician.
You will lie down on the table. The pictures are then taken. You will change your body to other positions to provide different views.
How to Prepare for the Test
Tell the health care provider if you are pregnant. Remove all jewelry. You will wear a hospital gown.
How the Test will Feel
The x-rays are painless. Changing position may cause discomfort.
Why the Test is Performed
The x-ray is used to look for:
- Degenerative conditions of bones in the hips, pelvis, and upper legs
What Abnormal Results Mean
Abnormal results may suggest:
- Pelvic fractures
- Arthritis of the hip joint
- Tumors of the bones of the pelvis
- Sacroiliitis (inflammation of the area where the sacrum joins the ilium bone)
- Ankylosing spondylitis (abnormal stiffness of the spine and joint)
There is low radiation exposure. However, pregnant women and children are more sensitive to the risks of x-rays.
