DEXA or Bone Densitometry
Bone Densitometry or DEXA (Dual Energy X-ray Absorptiometry) scans provide physicians with an early diagnostic tool by which to determine whether osteoporosis treatment is needed. The patient that benefits most from this type of testing is early post-menopausal women. During a comprehensive examination with DEXA, you will lay comfortably still on a padded table while the DEXA unit scans two or more areas, usually the fracture-prone hip and spine. Unlike typical X-ray machines, radiation exposure during bone densitometry is extremely low. The entire process takes 10-15 minutes to complete, depending on the number of sites scanned. It involves no injections or invasive procedures, and you may remain completely clothed.
Preparing for Bone Densitometry
Unless instructed otherwise, eat normally on the day of the exam, but avoid taking calcium supplements for at least 24 hours prior to your appointment. Wear loose, comfortable clothing. Casual attire without zippers, buttons, grommets or any metal are preferred. You should not have had a barium study, radio-isotope injection, oral or IV contrast material from a CT or MRI within two weeks prior to your DEXA test.
