Dexascan Testing - Bone Density Scan
Nearly 28 million Americans have--or are at risk for osteoporosis.  This disease occurs when bone density decreases, leading to fragile bones and an increased risk of fracture.  The DEXA Scan can precisely determine the level of bone density at the target areas and allow physicians to recommend treatments early.

Osteoporosis is responsible for 1.5 million fractures in the United States each year, and half of women over 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 the non-bony tissues of the body. Dexascan provides a measurement of the bone mineral density so your physician can determine if you have osteoporosis. If you are already being treated for osteoporosis, a Dexascan can monitor the effects of therapy.

How to prepare for this 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.
