DEXA (Dual-Energy X-ray Absorptiometry) is the gold standard for measuring bone density and assessing osteoporosis risk. Very low radiation dose. GP consultation at Mediway + referral to our accredited imaging partner + results interpreted at Mediway follow-up.
Medically reviewed by Dr. Qiao Yufei, MD
DEXA scan prices in Singapore typically range from $100 to $300 at accredited imaging partners, depending on whether one or multiple body sites (lumbar spine, hip, wrist) are scanned. Mediway GP consultation for referral is $38. Medisave may be used when DEXA is ordered for clinical investigation. All prices GST-inclusive and indicative, confirmed at booking.
DEXA (Dual-Energy X-ray Absorptiometry) uses two low-dose X-ray beams to measure bone mineral density. It is the gold standard test recommended by the World Health Organization and the International Society for Clinical Densitometry (ISCD) for diagnosing osteoporosis and assessing fracture risk.
The scan measures bone density at the lumbar spine and hip: the two sites most prone to osteoporotic fracture. Some scans also include the forearm. Results produce a T-score (comparison to a young healthy adult) and a Z-score (comparison to age-matched peers) that inform diagnosis and treatment decisions.
DEXA is quick (10-20 minutes), painless, and uses extremely low radiation, about 0.001 mSv, roughly a few hours of natural background radiation and significantly less than a standard chest X-ray. No injections, no enclosed scanner, no sedation.
Singapore MOH and international guidelines recommend DEXA screening for adults at risk of osteoporosis. Mediway GP will assess whether a scan is appropriate for your situation.
Standard screening recommendations:
Risk factors that warrant earlier DEXA:
DEXA reports a T-score comparing your bone density to a healthy young adult. The World Health Organization (WHO) classification:
Bone density within the expected range. General bone-health advice: adequate calcium and vitamin D, weight-bearing exercise, and avoiding smoking and excess alcohol.
Reduced bone density: not yet osteoporosis, but at elevated fracture risk. Lifestyle interventions, address underlying risk factors, repeat DEXA in 2-5 years. Medication considered if additional risk factors.
Significant bone density loss. Fracture risk is high. Treatment typically includes calcium and vitamin D, plus pharmacological therapy (bisphosphonates, denosumab, or others). Repeat DEXA in 1-2 years to monitor response.
Results also include a Z-score comparing your bone density to age-matched peers, useful for assessing whether bone loss is due to age or another cause. Your GP will interpret the full report and recommend appropriate next steps.
Indicative pricing at our accredited imaging partner. Actual rates confirmed at booking. All prices GST-inclusive.
Medisave eligibility: Medisave may be used when DEXA is ordered for clinical investigation (e.g. suspected osteoporosis, post-fracture, steroid bone loss). Typically not applicable for pure screening. Confirm eligibility with Radlink, our accredited imaging partner, at booking.
Three-step process. Assessment and interpretation at Mediway; scan at our accredited imaging partner.
GP assesses osteoporosis risk factors, confirms DEXA is appropriate, and issues a referral letter. We advise on preparation, which is minimal for most patients.
Attend the accredited imaging partner. Scan takes 10-20 minutes. You lie on a table while a scanner arm passes over your hip and spine. No injections, no tubes, no sedation.
Radiologist's report returns in 3-7 working days. Return to Mediway for follow-up. The GP explains your T-score, Z-score, and fracture risk, and recommends next steps including lifestyle measures and medication if appropriate.
DEXA scan prices typically range from $100 to $300 at accredited imaging partners, depending on whether one or multiple body sites are scanned. Mediway GP consultation is $38. Medisave may apply when clinically indicated.
DEXA (Dual-Energy X-ray Absorptiometry) is the gold standard scan for measuring bone density. It uses very low-dose X-ray to measure calcium and bone mineral content, diagnosing osteoporosis, assessing fracture risk, and monitoring treatment response.
Yes. DEXA uses very low-dose X-ray, about 0.001 mSv, equivalent to a few hours of natural background radiation. One of the lowest radiation doses in medical imaging, significantly lower than a standard chest X-ray.
Women 65+ and men 70+ as routine screening. Earlier if risk factors are present: post-menopausal, previous low-impact fracture, long-term steroid use, family history, low body weight, smoking, heavy alcohol, or certain chronic conditions.
10-20 minutes. You lie on a table while a scanner arm passes over your hip and lumbar spine. No injections, no enclosed scanner, no preparation needed for most patients. Results return in 3-7 working days.
Minimal preparation. Avoid calcium supplements for 24 hours before the scan. Wear loose clothing without metal (zippers, buttons); a gown may be provided. Inform your doctor if you have had recent CT with contrast, nuclear medicine, or barium studies in the past week.
Yes. A GP consultation ($38) assesses osteoporosis risk, confirms DEXA is appropriate, and provides the referral letter. The referral ensures the correct scan protocol and enables Medisave claim where applicable.
DEXA reports a T-score. T-score −1 or higher is normal. Between −1 and −2.5 is osteopenia (reduced density). −2.5 or lower is osteoporosis. Your GP explains your specific results and advises on next steps.
Medisave may be used for DEXA when ordered for clinical investigation (suspected osteoporosis, post-fracture, steroid-induced bone loss). Typically not for pure screening. The imaging partner and your GP will advise on eligibility before the scan.
For osteoporosis monitoring during treatment: every 1-2 years. For untreated osteopenia: every 2-5 years. Frequency depends on your T-score, risk factors, and treatment response. Your GP recommends the appropriate schedule.
