Key Takeaways
- A DEXA scan is the gold-standard test for measuring bone density and catching early signs of osteopenia or osteoporosis.
- Your results come back as a T-score, which tells you and your doctor exactly where your bone health stands.
- Catching bone loss early gives you time to take action before a fracture happens.
- The scan itself is painless, quick, and requires very little preparation.
- Pittsburgh Imaging and Wellness has provided trusted diagnostic imaging in Western Pennsylvania since 1993, and our team is ready to help you take the next step with a DEXA scan near you.
What a DEXA Scan Measures and How It Works
If your doctor has mentioned bone density testing, you may be wondering exactly what that involves. DEXA, short for Dual-Energy X-ray Absorptiometry, is a noninvasive imaging test that uses very low levels of X-ray energy to measure the mineral content and density of your bones, most often at the hip and spine.
During the exam, you'll lie flat on a padded table while a scanning arm passes slowly over your body. The machine sends two different X-ray beams through your bones, and a computer calculates your bone density based on how much energy passes through. The test is completely painless and typically takes just 10 to 15 minutes at Pittsburgh Imaging and Wellness.
What Your Results (T-Scores) Actually Mean
Once your scan is complete, your results are reported as a T-score, which compares your bone density to that of a healthy young adult. According to Mayo Clinic, a T-score of -2.5 or lower indicates osteoporosis, while a T-score between -1 and -2.5 is considered osteopenia. In most cases, a T-score above -1 falls within the normal range.
Understanding Your T-Score
| T-Score Range | What It Means |
|---|---|
| -1.0 and above | Normal bone density |
| -1.0 to -2.5 | Osteopenia (early bone loss) |
| -2.5 or lower | Osteoporosis |
It's worth noting that osteopenia isn't a diagnosis to panic over. It's an early warning sign, and often the perfect window to make changes that protect your bones before more significant loss occurs.
How Early Detection Can Prevent Fractures
Bone loss tends to happen quietly. Many people don't notice any symptoms until a fracture occurs, often from a fall that wouldn't have caused an injury in someone with healthy bone density. That's exactly why early screening matters so much.
Your doctor may recommend a DEXA scan if you:
- Are female and over age 65 (or under 65 with risk factors)
- Are male and over age 70
- Have experienced a bone fracture after age 50
- Have a family history of osteoporosis
- Have a small or thin body frame
- Have had ovary removal
- Take certain medications, such as steroids or anticonvulsants
- Have low calcium intake or low physical activity
- Smoke or consume excessive alcohol
Identifying bone loss early gives you and your doctor time to slow or even reverse the progression before a fracture happens, rather than reacting after one already has.
What Happens After You Receive Your Results
After your scan, your results are sent to your referring provider, often within just a few hours. From there, your doctor will review your T-score alongside your overall health history and any additional risk factors to determine the best path forward.
Depending on your results, your provider may recommend simply repeating the scan in a year or two to monitor changes, or they may suggest more immediate lifestyle or medical intervention.
Lifestyle and Medical Next Steps Based on Findings
Whether your DEXA scan shows normal bone density, osteopenia, or osteoporosis, there are concrete steps you can take:
- Increase calcium and vitamin D intake through diet or supplements, as recommended by your provider.
- Add weight-bearing exercise to your routine, such as walking, dancing, or light resistance training.
- Limit alcohol and avoid smoking, both of which are linked to accelerated bone loss.
- Review your medications with your doctor, since some, like long-term steroid use, can contribute to bone thinning.
- Follow up with repeat DEXA scans as recommended to track your bone health over time.

Frequently Asked Questions
What is a DEXA scan used for?
A DEXA scan measures bone mineral density, most often at the hip and spine, to identify osteopenia or osteoporosis before a fracture occurs.
What is considered a normal DEXA scan result?
A T-score of -1.0 or higher is generally considered within the normal range. Scores between -1.0 and -2.5 indicate osteopenia, and scores of -2.5 or lower indicate osteoporosis.
How much does a DEXA scan cost?
Cost varies, but DEXA scans are typically covered by insurance when medically necessary, particularly for patients over 65 or those with known risk factors. Pittsburgh Imaging and Wellness accepts most major insurance plans and can help verify your benefits ahead of time.
How often should I get a bone density test near me?
This depends on your individual risk factors and prior results. Your doctor will typically recommend a screening schedule, often every one to two years, based on your age, health history, and previous scans.
Is a DEXA scan safe?
Yes. DEXA scans use much lower radiation levels than a typical chest X-ray, making them a safe option for routine bone health screening.
