What a DEXA scan shows
A DEXA (dual-energy X-ray absorptiometry) scan is the gold standard for body composition. A whole-body scan shows your body fat %, lean muscle by region, visceral fat and bone mineral content. It's especially useful if you're on a GLP-1 like Wegovy or Mounjaro, training for performance, or tracking healthy ageing. Learn how to read every number on your DEXA report.
A bone density scan is different: it measures the hip and spine to check for osteopenia and osteoporosis and estimate fracture risk, and gives you a T-score and Z-score. If you want body fat, muscle and visceral fat numbers, book the whole-body composition scan.

Do I need a GP referral for a DEXA scan in London?
No. At DEXA London you complete a short self-referral form and the clinic checks it against its eligibility criteria. If a scan may not be suitable, the clinic will contact you and may suggest seeing your GP or a specialist first.
What's the difference between a body composition scan and a bone density scan?
A whole-body DEXA body composition scan measures body fat, lean muscle by region, visceral fat and bone mineral content. A bone density scan focuses on your hip and spine to check for osteopenia and osteoporosis and estimate fracture risk; it doesn't report body fat or muscle.
How long does a DEXA scan take?
The scan itself takes about 10 minutes on an open table, with nothing enclosed. Allow extra time for arrival, changing into a gown and paperwork.
When do I get my results?
At DEXA London, body composition results come the same day as a patient-friendly PDF report. Bone density scans are reported by UK consultant rheumatologists and emailed to you, so you can share them with your GP.
How do I prepare for a DEXA scan?
Wear comfortable clothes with no metal and remove jewellery. Skip calcium supplements for 24 hours beforehand, and tell the staff if you recently had a barium or contrast exam. Don't get scanned if you are or might be pregnant.
How do I get to DEXA London?
The clinic is at 86 Harley Street, about a 5-minute walk from Regent's Park (Bakerloo line), 7 minutes from Great Portland Street and 10 minutes from Oxford Circus. It is inside the Congestion Charge and ULEZ zones; paid parking is available around Cavendish Square.
How often should I get a DEXA scan?
For body composition, most people rescan every 8-12 weeks while actively changing their training, nutrition or medication. Bone density is usually repeated every 1-2 years or as your doctor advises. Use the same scanner each time so results are comparable.
Is a DEXA scan safe?
Yes. DEXA uses a very low dose of X-ray, typically lower than a standard chest X-ray. If you are or might be pregnant, don't get scanned. Read more: is a DEXA scan safe?
