Why This Test Is Done

Your healthcare provider may recommend this test if you have symptoms like bone pain, a history of fractures, or risk factors for osteoporosis, such as aging, low body weight, or certain medications. It’s also used to monitor bone health in people with conditions like rheumatoid arthritis or hormonal imbalances.

How the Test Works

During the scan, you’ll lie still on a table while low-dose X-rays pass through your pelvis. The machine measures how much the X-rays are absorbed by your bones, which helps calculate your bone density.

What to Expect Before the Test

No special preparation is needed, but you may be asked to remove jewelry, clothing, or metal objects that could interfere with the scan. Wear comfortable clothing and bring your medical records if you have any concerns about the test.

What to Expect During the Test

The scan takes about 10–15 minutes. You’ll feel a slight pressure from the table but no pain. The technician will explain the process and ensure you’re comfortable throughout.

Frequently asked questions

How long does the pelvic bone density scan take?
The scan itself typically takes about 10–15 minutes, but the entire process—from preparation to results—may take longer depending on your healthcare provider’s workflow.
Is there any pain or discomfort during the scan?
No, there is usually no pain. You may feel slight pressure from lying on the table, but the scan itself is painless.
What if my results show low bone density?
If your results indicate low bone density, your provider will discuss next steps, which may include lifestyle recommendations (like diet and exercise), medications, or further testing to manage your condition.
