DEXA Scan (Investigation Guide)
A DEXA scan is a low-radiation X-ray test that measures bone density at the hip and spine, used to diagnose osteoporosis and assess fracture risk.
Why it's done
- diagnose osteoporosis or osteopenia
- assess fracture risk
- monitor bone density over time or during treatment
What we offer
- a quick 10-15 minute scan with a very small radiation dose
- no special preparation beyond comfortable clothing
- a clear T-score result explained at your visit
Understanding DEXA results
DEXA measures bone mineral density at the hip and spine. T-scores and Z-scores must be interpreted with fracture history and clinical risk factors because bone density is only one part of fracture risk.
Preparation and scan limitations
The scan is quick and uses very low radiation. Tell the team about pregnancy and recent contrast, barium or nuclear-medicine tests. Metalwork, arthritis, spinal degeneration and positioning can affect measurements.
Results and UK-wide review
DEXA findings and treatment options can usually be reviewed securely by video. Blood tests or spinal imaging may be arranged locally when secondary causes or vertebral fractures are suspected.
