What the test shows

An AP pelvis X-ray provides a front-to-back view of the pelvic bones and parts of both hip joints. The radiologist looks for fractures, joint changes, alignment abnormalities, and other visible findings.

Why it is performed

This test may be ordered after a fall, injury, or traffic collision, or when pain in the pelvis, hips, groin, or lower back suggests a bone or joint problem. It can also be used to assess arthritis or monitor certain conditions.

How the test is done

You will usually stand or lie on the X-ray table while the machine takes images from the front. You may be asked to hold still or briefly change positions. The procedure is generally quick and does not require an injection or removal of clothing unless the area is covered.

Preparation and safety

Wear comfortable clothing and tell the care team if you might be pregnant, because radiation exposure is avoided or minimized when possible. Remove jewelry, belts, and other metal objects near the pelvis if instructed.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Does a pelvis X-ray require fasting?
Usually not. You can generally eat and drink as normal unless the imaging facility gives you different instructions.
Will the test be painful?
The X-ray itself is not painful. You may feel brief discomfort or pressure when asked to stand, reposition, or hold still, especially if you have a painful injury.
How soon will the results be available?
A radiologist usually reviews the images and sends a report to your ordering clinician. The timing can vary, so contact the care office if you need the results for a treatment decision or follow-up appointment.
