Dexa Scan (bmd)

A DEXA scan (Dual-Energy X-ray Absorptiometry) is a non-invasive imaging test primarily used to measure bone mineral density (BMD) and assess the risk of osteoporosis and fractures. It uses low-dose X-rays at two different energy levels to evaluate bone mass and provide detailed images of bone structure. DEXA is considered the gold standard for diagnosing osteoporosis and monitoring bone health over time.

The procedure is quick, typically taking about 10–20 minutes, with the patient lying on a table while a scanning arm passes over the body, usually focusing on the hip, spine, or sometimes the forearm. The scan can also measure body composition, including the percentage of body fat and lean mass, which is useful for evaluating overall health, especially in individuals undergoing weight management or fitness programs. DEXA scans are safe and involve minimal radiation exposure, making them suitable for long-term monitoring. The results are used by healthcare providers to guide treatment decisions, especially in individuals at risk for bone loss or fractures.
