DEXA Scan

A DEXA (Dual-Energy X-ray Absorptiometry) scan is a quick, painless scan that uses very low levels of X-rays to measure your body composition — how much fat, muscle, and bone you have, and where it is distributed. It is one of the most accurate ways to track changes in your body during a weight loss programme.

Dual-Energy X-ray Absorptiometry (DEXA) is a medical imaging modality that uses two X-ray beams at different energy levels to differentiate between bone mineral, lean soft tissue, and adipose tissue. Originally developed for osteoporosis assessment, DEXA now provides gold-standard whole-body composition analysis with a precision error of approximately 1–2% for total body fat percentage, making it superior to BIA and skinfold calipers for longitudinal monitoring.

Tracking weight alone on a scale does not reveal whether you are losing fat or valuable muscle. A DEXA scan gives Dr. Joseph Wang and our Accord Medical team a precise baseline and progress map, ensuring your weight loss plan preserves lean mass while targeting fat — critical for long-term metabolic health.
