A Dual-Energy X-ray Absorptiometry (DEXA) machine uses x-ray to analyze body composition in terms of fat, muscle mass, and resting metabolic rate. This can also analyze bone strength, or bone mineral density, making it different from other conventional body composition scales or devices.
The machine
Quick – lasts 15 minutes
Painless – simply lie down
Open – not confining like a CT or MRI
Safe – no more radiation than a 1.5-hour flight
Why?
Bone strength – Assess bone mineral density to gauge risk for future fracture.
Muscle mass – Assess total skeletal muscle to gauge risk for sarcopenia/frailty.
Fat – Assess fat around internal organs which is a risk for cardiovascular disease.
Goal setting – In-depth measurements of each part of your body including daily caloricneeds.
Monitoring – Gauge success of your treatment and rehabilitation for before and after
How?
No calcium supplements 24 hours prior to test
No food 3 hours prior to test
Assessment with doctor both before and after your test
