What is a Bone Density Scan?

Bone density testing is used to assess the strength of the bones and the probability of fracture in persons at risk for osteoporosis. It is referred to as bone densitometry or bone mineral density scan (BMD).

Osteoporosis is a disease in which there is a loss of bone mass and destruction of bone tissue. This process causes weakening of the bones and makes them more likely to break. Osteoporosis affects over 10 million Americans, with women four times more likely to develop osteoporosis than men. Another 34 million people have low bone mass or osteopenia. Osteopenia is generally considered the first step along the road to osteoporosis.

Most people today will get a bone density scan from a machine using a technology called Dual Energy X-ray Absorptiometry or DEXA for short. This machine measures the calcium in the bones in the spine, hip, total body and wrist, and calculates their density.

It is a simple, noninvasive procedure that takes just minutes. There is no pain or discomfort.

Bone Density Facts 

• Up to 30% of postmenopausal women in the U. S. have loss of bone density to the level of osteoporosis. An additional 54% have sub-optimal bone density.

• At least 90% of hip and spine fractures in elderly women can be attributed to low bone density.

• In 1995, osteoporosis-related fractures were associated with over 400,000 hospitalizations and over 2.5 million doctor's visits.

• Bone mineral density (BMD) is a measured calculation of the true mass of bone.

• BMD analysis is recommended for women under the age of 65 with risk factors and for all women over the age of 65.

• By measuring BMD, it is possible to predict fracture risk in the same manner that measuring blood pressure can help predict the risk of stroke.

• Dual X-ray absorptometry (DXA) is quick, painless and the preferred method to measure BMD.

• Osteoporosis has many available treatment options once the diagnosis is made.
