Why This Test Is Done

Your healthcare provider may recommend this test if you have symptoms like back pain, numbness, weakness, or if they suspect conditions like osteoporosis, spinal stenosis, or prior trauma. It’s also used to monitor conditions like scoliosis or after spinal surgery.

What to Expect Before the Test

No special preparation is needed. You’ll likely wear a hospital gown, and a technician will position you on an X-ray table. You may need to hold still for a few seconds while the image is taken.

During the Test

The test involves lying on your stomach or back while the X-ray machine takes images from two angles: front-to-back (anteroposterior) and side-to-side (lateral). The radiation dose is minimal and safe for most adults.

After the Test

You can return to your normal activities immediately. If you had contrast dye (uncommon for spine X-rays), drink plenty of fluids afterward to help it pass through your system.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

This test plays a critical role in identifying structural abnormalities in the spine, such as fractures, degenerative disc disease, or congenital spinal deformities. It helps guide treatment decisions, including physical therapy, medications, or surgical interventions when needed.

Frequently asked questions

Will I feel any pain or discomfort during the test?
No, you shouldn’t feel pain. Some people may experience mild pressure from the X-ray table, but the images are painless. If you have severe back pain, let the technician know so they can adjust your position.
How long will the results take to come back?
Results are typically available within a few hours to a couple of days, depending on your healthcare provider’s workflow. Your doctor will discuss them with you during a follow-up visit.
Can I eat or drink before this test?
No special diet is required. You can eat and drink normally unless your provider instructed otherwise, as this test doesn’t involve fasting.
