What Is an X-ray Used For?

X-rays of the lumbar spine are typically used to diagnose conditions such as herniated discs, spinal stenosis, degenerative disc disease, fractures, or scoliosis. They can also help evaluate the success of surgical procedures or monitor chronic spinal conditions over time.

Preparation for the Test

No special preparation is needed for this test. You may be asked to remove jewelry, clothing covering the lumbar area, or any metal objects that could interfere with the imaging. You’ll likely be asked to stand or lie on your stomach for the images.

During the Test

The test involves taking multiple X-ray images from different angles (usually anterior-posterior and lateral views) to provide a detailed view of your lumbar spine. You’ll be positioned carefully to ensure clear images, and you may hear a clicking sound as the X-ray machine moves.

After the Test

You can resume your normal activities immediately after the X-ray. There are no side effects, but you may feel mild discomfort from the positioning. If you have any concerns or notice unusual symptoms, contact your healthcare provider.

Frequently asked questions

Why might my doctor order this test?
Your doctor may order a lumbar spine X-ray to investigate symptoms like back pain, numbness, weakness, or neurological issues. It can also be used to check for spinal abnormalities before surgery, evaluate trauma, or monitor chronic conditions like osteoporosis or degenerative disc disease.
What are the risks or side effects of this test?
The primary risk of an X-ray is exposure to low levels of radiation, which is generally considered safe when used appropriately. Rarely, radiation exposure can cause temporary skin redness or mild fatigue, but these are uncommon. If you’re pregnant or have concerns about radiation exposure, discuss this with your doctor.
How long will it take to get my results?
Results from a lumbar spine X-ray are typically available within a few days to a week, depending on your healthcare provider’s workflow. Your doctor will review the images and discuss findings with you during your follow-up visit.
