Did You Know?

Bone density scanning, also called dual-energy x-ray absorptiometry (DXA or DEXA) or bone densitometry, is an enhanced form of x-ray technology that is used to measure bone loss. DEXA is today's established standard for measuring bone mineral density (BMD).

 

Bone Densitometry

Bone DensitometryOsteoporosis is a progressive disease characterized by decreased bone density and increased bone fragility. It is a complex disease that may progress silently for decades – there may be no symptoms until fractures occur. Bone loss is the major risk factor that can be modified in mid-life to reduce fracture risk. Early detection is essential.

EMMC has a state-of-the-art Bone Densitometry machine made by General Electric. A complete body scan takes three minutes and requires no more from you than to lay down during the scan. The scan has a low level x-ray and is very safe.

In the United States, over 28 million people are at high risk of developing osteoporosis. Up to 1.5 million fractures a year are attributable to osteoporosis. Women are at the greatest risk. One third of Caucasian women over the age of 50 have osteoporosis, yet nearly 80% remain undiagnosed. After menopause, a woman’s risk of suffering an osteoporotic spine or femur fracture is 30% or three times that of a man’s.

Bone density testing is strongly recommended if you:

  • are a post-menopausal woman and not taking estrogen.
  • have a personal or maternal history of hip fracture or smoking.
  • are a post-menopausal woman who is tall (over 5 feet 7 inches) or thin (less than 125 pounds).
  • are a man with clinical conditions associated with bone loss.
  • use medications that are known to cause bone loss, including corticosteroids such as Prednisone, Actonel and Fosamax, various anti-seizure medications such as Dilantin and certain barbiturates, or high-dose thyroid replacement drugs.
  • have type 1 (formerly called juvenile or insulin-dependent) diabetes, liver disease, kidney disease or a family history of osteoporosis.
  • have high bone turnover, which shows up in the form of excessive collagen in urine samples.
  • have a thyroid condition, such as hyperthyroidism.
  • have a parathyroid condition, such as hyperparathyroidism.
  • have experienced a fracture after only mild trauma.
  • have had x-ray evidence of vertebral fracture or other signs of osteoporosis.
