• DEXA stands for Dual-Energy X-ray Absorptiometry, and is also known as a Bone Density Test. A Dexa scan is a quick, painless method of screening for osteoporosis.

• The most accurate method available for the diagnosis of osteoporosis. It is also considered an accurate estimator of fracture risk.

• Uses low-dose radiation, roughly one-tenth the does of a routine chest x-ray. The most common sites that are evaluated for a Dexa Scan are the spine and hip. The forearm may also be scanned if deemed necessary.

• A licensed Radiologic Technologist will perform the Dexa scan, and it will be read by a board-certified Radiologists. The results are then given to your physician, who will determine the proper course of action.

• Osteoporosis involves a gradual loss of calcium, causing the bones to become thinner, more fragile and more likely to break.

• Possible treatments for osteoporosis include taking calcium supplements, or taking prescription medications proven to decrease bone loss, such as Fosamax or Actonel. Your physician will determine the appropriate treatment.

• Continuous screenings, every 1-5 years, may be necessary. Your referring physician will determine how often you need this test.

• A Bone Density test should not to be confused with a Bone Scan, which is a nuclear medicine procedure in which a radio-nucleotide is injected to determine bone abnormalities.
