Bone Density (DEXA) Scan

The DEXA scan is the gold-standard test for measuring bone strength, essential for detecting osteoporosis early and assessing your future fracture risk.

About the Bone Density (DEXA) Scan

A DEXA (dual-energy X-ray absorptiometry) scan measures your bone mineral density using a very low dose of radiation. It is the most accurate way to detect osteoporosis — thinning of the bones that increases fracture risk — often before any fracture occurs. It is particularly valuable for post-menopausal women, older adults, and anyone with risk factors for bone loss, allowing timely steps to protect bone health.

Preparation and turnaround

The scan is quick, painless and non-invasive, requiring no fasting; you simply lie still while the scanner passes over you, taking around 10 to 20 minutes. You will be asked to remove metal objects. Results are usually available within one working day. Please tell our team beforehand if you are or may be pregnant.

Frequently asked questions

Who should have a bone density scan?

It is especially valuable for post-menopausal women, older adults, and anyone with risk factors for osteoporosis or previous fractures.

Is the scan uncomfortable?

No. It is painless and non-invasive — you simply lie still for around 10 to 20 minutes while the scanner passes over you.

Does it involve radiation?

It uses a very low dose of radiation, much less than a standard X-ray. Tell our team if you are or may be pregnant.
