DEXA (Dual Energy X-ray Absorptiometry) or bone densitometry uses low strength X-rays to measure the density and mineral content of your bones. The amount of X-ray used is very small - less than one-tenth of what is used in a chest X-ray. This test is a valuable tool for diagnosing osteoporosis, which often has no symptoms until you suffer a fracture. DEXA can diagnose the disease at its earliest stages, which means you can begin receiving treatment to protect your bones sooner.
