DEXA Bone Mineral Density (BMD) Scans Sydney
A DEXA Bone Mineral Density (BMD) scan is a quick, low‑dose X-ray test used to measure bone strength and diagnose conditions such as osteoporosis and osteopenia. It is the most accurate method for assessing fracture risk. At Advicon Imaging, Medicare‑eligible DEXA BMD scans are fully bulk‑billed.

Description of DEXA Bone Mineral Density (BMD)
A DEXA Bone Mineral Density (BMD) scan is the gold-standard test for evaluating bone health. It measures bone density at the spine, hips, and sometimes the forearm—areas most predictive of future fracture risk. Using dual low-energy X-ray beams, the scan provides precise measurements that help doctors diagnose osteoporosis, monitor bone loss, and guide treatment.
DEXA BMD is commonly recommended for postmenopausal women, adults with risk factors such as long-term steroid use, chronic medical conditions, previous fractures, early menopause, or family history of osteoporosis. It is also used to monitor the effectiveness of osteoporosis medications over time.
The scan is quick (about 10 minutes), painless, and non-invasive. You simply lie on a comfortable padded table while the scanning arm passes over the body. Radiation exposure is extremely low—much lower than a standard X-ray and safe for repeated monitoring when clinically required.
At Advicon Imaging, we use modern DEXA systems to provide accurate, reproducible measurements with clear and easy-to-understand reports. Medicare covers DEXA scans when specific medical criteria are met, and all eligible scans are bulk-billed.
Frequently Asked Questions
What is a DEXA BMD scan?
A DEXA BMD scan measures bone density to determine if you have osteoporosis, osteopenia, or normal bone strength.
Why has my doctor ordered this test?
Common reasons include:
- Age-related bone loss
- Menopause
- Previous fractures
- Long-term steroid use
- Chronic illnesses affecting bone health
- Monitoring osteoporosis treatment
Do I need any preparation?
Minimal preparation is required.
- Avoid calcium supplements for 24 hours before the test.
- Wear loose, metal-free clothing.
- Inform us if you may be pregnant.
What happens during the scan?
You will lie on a padded table while the scanner passes over you. The scan is painless and takes around 10 minutes.
Does it use radiation?
Yes, but the dose is extremely low—far lower than a normal X-ray.
Is the scan painful?
No. It is completely painless and non-invasive.
How often should I have a DEXA scan?
Your doctor may recommend a scan every 1–2 years depending on your risk factors and bone health history.
Can I drive afterwards?
Yes. You can return to all normal activities immediately.
When will my doctor receive the results?
Reports are usually available within 24–48 hours.
Is this scan bulk-billed?
Yes. All Medicare‑eligible DEXA BMD scans are fully bulk‑billed at Advicon Imaging.
