Bone Density Study (DEXA)

Bone densitometry, also called dual-energy x-ray absorptiometry, DEXA or DXA, uses a very small dose of ionizing radiation to produce pictures of the inside of the body (usually the lower (or lumbar) spine and hips) to measure bone loss. It is commonly used to diagnose osteoporosis, to assess an individual’s risk for developing osteoporotic fractures. DXA is simple, quick and noninvasive. It’s also the most commonly used and the most standard method for diagnosing osteoporosis.

DEXA can also be used to measure Body Mass Index (BMI), body composition and bone density. It shows precisely how fat is distributed to different parts of your body, distinguishing it from lean muscle and bone. The scan calculates your body’s shape and where you store fat.
