DEXA Scan Perth
Body Composition & Bone Density Assessment
What Is DEXA Scan Perth?
DEXA (Dual-Energy X-ray Absorptiometry) is the clinical gold standard for body composition assessment. Using two low-energy X-ray beams at different frequencies, it precisely differentiates bone mineral content, lean muscle mass, and fat tissue — providing a level of accuracy and anatomical detail that no other body composition tool can match.
Available on-site at The Longevity Lab Perth, our DEXA service produces detailed, regionally specific data — not just an overall body fat percentage, but a precise breakdown of fat and muscle distribution across the trunk, arms, legs, and android/gynoid regions. This data is clinically interpreted and provided in a clear, actionable report.
Note: DEXA uses very low-dose X-ray — approximately equivalent to 3 hours of background radiation exposure. It is not an MRI and does involve a minimal radiation dose.
What Does It Assess?
Total body fat percentage — overall body composition
Regional fat distribution — trunk, arms, legs, android (abdominal) and gynoid (hip) regions
Visceral fat mass — the metabolically active fat surrounding internal organs
Lean muscle mass — total and regional (invaluable for sarcopaenia assessment)
Bone mineral density (BMD) — at the spine and hips, with T-score and Z-score comparison
Fat mass index & lean mass index — normalised to height for meaningful comparison
Android-to-gynoid fat ratio — a key cardiovascular risk marker
Who Should Consider This?
- Those embarking on a fitness, weight management, or body recomposition programme who want a precise baseline
- Athletes and recreational exercisers wanting objective data on muscle mass, fat distribution, and training response
- Individuals aged 40+ wanting bone density assessment for osteopaenia or osteoporosis risk
- Those with metabolic conditions (type 2 diabetes, metabolic syndrome) wanting visceral fat quantification
- Anyone wanting a scientifically accurate alternative to BMI or consumer body composition scales
