Who Should Get 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. The test, referred to as bone densitometry or
bone mineral density scan (BMD), is a simple,
noninvasive procedure that takes just minutes.

Bone density scan facts
- About 40% of postmenopausal women in the U.S. have osteopenia (low bone density). An additional 7% have osteoporosis (substantially low bone density).
- One in three women and one of five men over the age of 50 will experience a bone fracture related to osteoporosis.
- About 33% of people who suffer a hip fracture are totally dependent or in a nursing home in the year following the fracture, stressing the importance of early detection and appropriate therapy.
- Bone mineral density (BMD) estimates the true mass of bone.
- BMD analysis is recommended for women between ages 50 and 65 with risk factors for osteoporosis and for all women over the age of 65. In addition, men and women taking certain medications or having certain diseases should discuss testing with their doctor.
- 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.
- DXA (or DEXA) is quick, painless, and the preferred method to measure BMD.
- Osteoporosis has many available prescription and nonprescription treatment options once the diagnosis is made.
What is osteoporosis?
Osteoporosis is a medical condition that is characterized by bones that are less dense than, and thus not as strong as, normal bone. Osteoporosis increases the risk of breaking a bone (fracture) with even minor trauma, such as a fall from standing height, or even from a cough or sneeze. Unfortunately, people often do not realize they have osteoporosis until either they have a fracture or have a screening test ordered by their doctor to check for osteoporosis. Osteoporosis and low bone mass affect an estimated 44 million Americans. Of those, 10 million have osteoporosis, and the remaining 34 million have a lower than normal bone mass (medically termed osteopenia) and are at higher risk of developing osteoporosis. Women are four times more likely to develop osteoporosis than men. Other health risk factors include older age, family history of osteoporosis, small and thin stature, inactive lifestyle, smoking, alcohol, and use of certain medications, including steroids.
