Bone Density Scan

Bone Density

Bone Density Scan

Bone density testing is used to assess the strength of the bones and the probability of the fracture in person at risk for osteoporosis. It is a simple non-invasive procedure that takes just minutes.

In this test, you will lie down on a table while your body is scanned with an x-ray imager that passes overhead. The procedure is performed while you are fully clothed and typically takes 10 minutes.

Your hips and spine are usually checked because they are the bones most at risk for dangerous density changes.

The results are interpreted by the radiologist and sent to your referring physician.


Most of a person’s bone mass is achieved by early adulthood. After that time, the bone mass gradually declines throughout the rest of a person’s life. There is a normal rate of decline in bone mass with age of a person’s life. There is a normal rate of decline in bone mass with age in both men and women. For women, in addition to age, the menopause transition itself causes an extra degree of bone loss. This loss is greatest in the first three to six years after menopause. Since women have a lower bone mass to begin with in comparison with men, the ultimate result is a higher risk of fracture in postmenopausal women as compared to men of the same age.

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