Key Takeaways
- DEXA scan measures bone mineral density to detect osteoporosis and fracture risk
- The test takes 10-15 minutes and uses very low radiation (1/10th of a chest X-ray)
- DEXA scan cost in Dubai typically ranges from AED 350 to AED 700
- Results are reported using T-scores: above -1.0 is normal, below -2.5 indicates osteoporosis
- Recommended for women 50+, men 60+, and those with fracture history or risk factors
A DEXA scan, also known as a DXA scan, is a quick, painless imaging test that measures bone density and helps detect bone loss before fractures happen. It's the most accurate way to diagnose osteoporosis, assess fracture risk, and monitor bone health over time. The scan uses very low-dose X-rays and is usually completed within 10–15 minutes.
This test is commonly recommended for adults over 50, postmenopausal women, people with frequent fractures, or anyone with risk factors for bone thinning. Doctors also use DEXA scans to track treatment results when bone-strengthening medications are prescribed.
What Is a DEXA Scan and Why Is It Done?
A DEXA scan measures bone mineral density (BMD), which shows how strong or fragile your bones are. The most common areas scanned are the lower spine, hip, and sometimes the forearm because fractures in these areas are more likely and more serious.
The main goal is early detection. Bone loss often happens silently, without pain or warning signs. By identifying changes early, doctors can suggest lifestyle changes or treatment before fractures occur. This is especially important for people with family history, long-term steroid use, or hormonal changes.
How a DXA Scan Works
The scan uses two low-energy X-ray beams that pass through the bone. By comparing how much of each beam is absorbed, the system calculates bone density. The radiation exposure is extremely low, much less than a standard chest X-ray.
During the scan, you'll lie flat on a padded table while a scanning arm moves slowly over your body. You don't enter a tunnel, and there's no noise or discomfort. The process is simple, calm, and doesn't require recovery time afterward.
Who Should Get a DEXA Scan?
Many people assume bone tests are only for older adults, but that's not always true. Doctors recommend DEXA scans based on age, health history, and risk factors rather than symptoms alone.
People commonly advised to get this test include:
- Women aged 50+ and men aged 60+
- Postmenopausal women
- Individuals with frequent fractures or height loss
- Long-term steroid users
- People with thyroid, hormonal, or autoimmune conditions
If you've already had imaging like an MRI scan or digital X-ray for bone or joint issues, a DEXA scan adds a different layer by measuring bone strength rather than structure.
What Happens During the Test?
Preparation is minimal. You can eat normally and take your medications unless told otherwise. The only thing to avoid is calcium supplements for 24 hours before the scan.
You'll be asked to remove metal objects such as belts or jewelry. Once positioned, the technologist will guide you through simple instructions like staying still for a few seconds. The scan itself usually takes 10 to 15 minutes, and you can resume normal activities immediately afterward.
Understanding DEXA Scan Results
DEXA results are reported using T-scores and Z-scores. These numbers help doctors compare your bone density to healthy reference values.
T-Score Interpretation
| T-Score Range | Meaning |
|---|---|
| Above -1.0 | Normal bone density |
| -1.0 to -2.5 | Osteopenia (low bone density) |
| Below -2.5 | Osteoporosis |
Doctors don't rely on numbers alone. Your age, fracture history, and medical background are all considered before making treatment decisions.
DEXA Scan Cost in Dubai
Cost is one of the most common questions patients ask. In Dubai, a DEXA scan typically costs AED 350 to AED 700, depending on the clinic, scan area, and reporting detail.
Some insurance providers may cover the test if it's medically indicated, especially for osteoporosis screening or treatment monitoring. It's always best to check coverage beforehand, particularly if the scan is part of a wider diagnostic plan involving services like blood tests or hormonal assessments.
Is a DEXA Scan Safe?
Yes, it's considered very safe. The radiation exposure is extremely low: about 1/10th of a standard chest X-ray. This makes it suitable even for repeat scans when monitoring bone health over time.
However, it's usually avoided during pregnancy unless absolutely necessary. Always inform the clinic if there's any chance you might be pregnant.
How Often Should You Get a DEXA Scan?
The frequency depends on your initial results and risk level. People with normal bone density may only need a scan every 3–5 years, while those with osteopenia or osteoporosis may be advised to repeat it every 1–2 years.
Doctors use follow-up scans to see whether bone density is stable, improving, or declining. This helps adjust treatment plans and lifestyle advice more accurately.
How DEXA Differs From Other Imaging Tests
A DEXA scan is often confused with other imaging tests, but its purpose is unique. While X-rays and MRI scans show bone structure or injury, DEXA focuses purely on bone strength.
It's also different from CT scans, which use much higher radiation and are not designed for routine bone density screening. That's why DEXA remains the global standard for osteoporosis diagnosis.
Why Early Bone Density Testing Matters
Bone loss doesn't cause pain until a fracture happens. Hip and spine fractures, in particular, can seriously affect mobility and quality of life. Early testing allows doctors to recommend changes such as diet adjustments, supplements, exercise routines, or medication before serious damage occurs.
For people with chronic conditions or hormonal changes, regular monitoring becomes an important part of long-term health planning.

Final Thoughts
A DEXA scan is one of the simplest yet most important tests for long-term bone health. It helps catch bone loss early, guides treatment decisions, and reduces the risk of fractures that can seriously affect daily life. With low radiation, quick results, and no recovery time, it's an easy step toward better health planning.
If you're unsure about your bone strength or fall into a higher-risk group, getting tested sooner rather than later can make a real difference. Accurate diagnosis leads to timely care, and timely care protects mobility, independence, and overall quality of life.
