The standard diagnostic imaging test that measures bone mineral density to assess bone health.
A medical imaging test using dual-energy X-ray absorptiometry to measure bone mineral density by comparing the absorption of two X-ray energy levels. It is the gold standard for diagnosing osteoporosis and assessing fracture risk.
DEXA (Dual-Energy X-ray Absorptiometry) is a quick, non-invasive imaging technique that exposes patients to minimal radiation—less than a standard chest X-ray. The test compares bone density at the lumbar spine, femoral neck, and total hip against reference values, producing a T-score that classifies bone health as normal, osteopenic, or osteoporotic. DEXA is the preferred diagnostic tool because it is accurate, reproducible, affordable, and widely available. Results guide clinical decisions about whether treatment is needed and help monitor the effectiveness of bone health interventions over time. The test is particularly important for postmenopausal women, men over 70, and individuals with risk factors for bone loss.
Provides objective quantification of bone mineral density through imaging, enabling diagnosis of bone disorders and assessment of fracture risk to guide treatment decisions.
Discuss with your healthcare provider whether DEXA screening is appropriate based on your age, sex, and risk factors. Schedule repeats every 1-2 years if you have osteopenia or are undergoing treatment to monitor progress.
DEXA scanning is the essential diagnostic tool for accurately assessing bone health and fracture risk.
