DEXA Scan
A DEXA scan is a quick, low-radiation scan that precisely measures body fat percentage, muscle mass, and bone density — the gold standard for body composition analysis.
Patient-Friendly Explanation
A DEXA scan is a quick and painless scan that measures your body fat percentage, muscle mass, and bone density. Unlike a regular scale, it shows exactly where fat is stored in your body, giving you and your doctor a precise picture of your health.
Clinical Definition
Dual-Energy X-ray Absorptiometry (DEXA) is a low-radiation imaging technique that quantifies bone mineral density and body composition by measuring the differential attenuation of two X-ray beams. It provides regional and total-body measurements of fat mass, lean mass, and bone mineral content, making it the gold standard for body composition analysis in clinical settings.
Why It Matters
DEXA scanning provides objective, precise baseline and follow-up data for weight management patients, enabling clinicians to track changes in visceral fat and lean muscle mass — metrics far more meaningful than BMI or scale weight alone.
