What Is A DXA Scan?
A DXA scan (dual-energy X-ray absorptiometry), commonly referred to as a DEXA scan or bone density test, is a painless imaging test that uses low-dose X-rays to measure bone density. It helps detect osteoporosis, assess your risk of fractures, and monitor bone health over time. The scan usually targets areas most likely to fracture, such as the hip and spine, and is considered the gold standard for evaluating bone strength.

Frequently asked questions about DXA Scans
-
A DXA scan can take 10 to 20 minutes, depending on the body part and purpose of the scan.
-
The cost of your DXA scan will depend on your insurance. After your provider prescribes a DXA scan, our Pre-registration and Authorization Department will confirm the price with you. Many insurance plans cover bone density scans for women 50 and older every two years.
If your insurance does not cover a DXA scan, you can choose to self-pay. Our Central Pricing Office will work with you to arrange your payment schedule.
-
Both terms refer to the same procedure. DEXA is a commonly used abbreviation.
-
Both tests are used to evaluate bone health but serve very different purposes.
- DXA scan (dual-energy X-ray absorptiometry): Measures bone density, helping detect osteoporosis and assess fracture risk. It focuses mainly on your hip, spine, and sometimes forearm. It uses low-dose X-rays and takes about 10–30 minutes.
- Whole-body bone scan: A nuclear medicine test that uses a small amount of radioactive material to look for bone abnormalities, such as infections, inflammation, arthritis, or cancer that has spread to the bones. It provides a full-body overview and is used when a broader diagnostic view is needed.
Your physician will recommend the appropriate scan depending on your specific symptoms and medical history.
-
Wear comfortable, loose-fitting clothes you can easily move in. Because metal interferes with the scanner, you will need to take off any jewelry as well as any clothing with metal details, such as zippers and buttons. Bras would need to be removed as well unless it’s a sports bra without any metal wiring or snaps on the back.
-
You will get your bone density results in 24 to 48 hours. The fastest and easiest way to see your results is through the PineApp. Baptist Health’s app helps you easily manage your healthcare — including viewing DXA scan results — from any mobile device.
-
Your DXA scan results are reported using a T-score and sometimes a Z-score. These scores compare your bone density to what is considered normal:
- T-score compares your bone density to that of a healthy young adult of the same sex.
- +1 to –1: Normal bone density
- –1 to –2.5: Low bone mass (osteopenia)
- –2.5 or lower: Osteoporosis
- Z-score compares your bone density to what’s typical for someone your age, sex, and size. A Z-score of –2.0 or lower may suggest a secondary cause for bone loss.
Your physician will explain your results in detail and help you understand what they mean for your health. Based on your score, you may be advised to increase calcium and vitamin D intake, begin medication, or make lifestyle changes to protect your bones.
-
Yes, you can drink coffee before a bone density test. However, avoid adding calcium-fortified milk or supplements to your coffee on the day of your scan, as these can affect your bone density readings. Always follow your physician’s specific instructions.
-
In most cases, yes, you can eat before a DXA scan. There is no fasting required. However, it’s best to avoid taking calcium supplements for at least 24 hours prior to your appointment, as they may interfere with scan accuracy. Let your care team know about any recent supplements or medications you’ve taken.
-
To ensure the most accurate results, please avoid the following before your DXA scan:
- Calcium supplements for 24 hours prior to the test
- Wearing clothing with metal zippers, snaps, or belts
- Recent imaging tests using contrast dye, such as CT scans or nuclear medicine studies — these may require a short waiting period
Be sure to inform your technologist if there’s any chance you could be pregnant or if you've had a recent scan with contrast.
-
Yes, a DXA scan uses very small amounts of X-ray radiation. However, the amount of radiation exposure is very low, and the benefits of the scan can positively impact your care.
-
No, the DXA scanner is painless and minimally invasive. While you lie or sit on a table, the scanner arm will pass over your body without touching you.
