DEXAscan - Bone Density Scan

Osteoporosis is responsible for 1.5 million fractures in the U.S. each year, and half of all women over age 50 can expect to suffer a fracture in their lifetime. Bone densitometry (DEXAscan) examinations measure the mineral content of the bone. A dual energy beam of very low dose X-rays passes through the area being examined. The detectors then compare the amount of X-rays absorbed by the bone to the amount absorbed by non-bony tissues. DEXAscan provides a measurement of the bone mineral density so your physician can determine if you have osteoporosis and recommend treatments early. If you are already being treated for osteoporosis, a DEXAscan can monitor the effects of therapy.

How to Prepare For A DEXAscan Test:

  • You should not have a barium study, radioisotope injection, oral or intravenous contrast material from a CT scan or MRI within seven days of your DEXAscan.
  •  Avoid taking calcium supplements for at least 24 hours prior to your appointment.
  •  Wear loose, comfortable clothing.
