Bone Densitometry (DEXA)
To accurately detect osteoporosis, doctors commonly use DEXA bone densitometry to measure bone mineral density (BMD). DEXA is a quick, painless procedure for measuring bone loss. Measurement of the lower spine and hips are most often done.
A peripheral dual-energy X-ray absorptiometry (P-DEXA) machine, which measures bone density in the wrist or forearm, is a portable unit that can be used in a doctor's office.
