Bone Density (DEXA)
A bone density scan (DEXA) measures the strength of your bones. It helps your doctor diagnose osteoporosis and understand your risk of fractures.
- Exam time: 10 to 15 minutes
- Preparation: No calcium supplements for 24 hours
- How it feels: Painless
What is it?
DEXA uses a very low dose of X-rays to measure the mineral content of your bones, usually in the hip and spine.
Osteoporosis often has no symptoms until a bone breaks. Knowing your bone density early helps your doctor decide if you need treatment.
Who is it for?
- Women after menopause
- Adults with risk factors for osteoporosis
- People taking medicines that can weaken bones
- Follow-up of osteoporosis treatment
