Bone densitometry, also called dual-energy x-ray absorptiometry or DEXA, uses a low dose of ionizing radiation to measure the density of your bones. The most common areas tested during a bone density scan often include the hip, spine, and forearm or wrist.
Common Uses of DEXA
DEXA is most often used to diagnose osteoporosis, a gradual thinning and weakening of the bones due to loss of calcium and structural changes that occur with age. Bone density tests can identify the severity of bone loss, determine the risk of fractures, and monitor the effectiveness of osteoporosis treatment.
