Bone Density Screening (DEXA)

Bone density screening, also called dual-energy X-ray absorptiometry (DEXA) or bone densitometry, is an enhanced X-ray that measures bone loss. DEXA is most often used to diagnose osteoporosis, a condition that generally affects women after menopause but may also be found in men. Bone density screening assesses your risk for developing fractures, as well.

Advanced Screening Technology

Portsmouth Regional Hospital offers bone density screening—the most accurate method available for diagnosing bone density loss—using the HOLOGIC bone densitometer, the leading dual-energy X-ray technology. DEXA screening is a simple, quick and noninvasive procedure that needs no anesthesia. The amount of radiation used is extremely small—less than one-tenth the dose of a standard chest X-ray and less than a day's exposure to natural radiation.

The Radiation Right safety program at Portsmouth Regional Hospital, where we adhere to nationally approved safety protocols that prevent accidental or excessive exposure, ensures you receive the lowest effective dose of radiation.
