DXA is used to measure which parameter?

Explanation:
DXA measures bone mineral density. It uses two-energy X-ray absorptiometry to quantify how much mineral is in a specific bone region, giving a BMD value often used to diagnose osteoporosis and assess fracture risk, especially at the hip and spine. This imaging is specific to bone health and does not assess serum calcium, blood glucose, or cardiac output, which require blood tests or other imaging modalities. BMD results are interpreted with T-scores and Z-scores to gauge bone health.
