Bone Density (DEXA Scan)

DEXA scanning has become the most widely used method for measuring bone mineral density. DEXA scanning more precisely documents small changes in bone mass and is also more flexible since it can be used to examine both the spine and the extremities. A scan of the spine, hip or the total body requires only one, two, or four minutes respectively. DEXA scanning is less expensive than alternative measuring processes, exposes the patient to less radiation, and is more sensitive and accurate at measuring subtle changes in bone density over time or in response to drug therapy.
