Frequently Asked Questions

Select question:

What is a bone density measurement?

A bone density measurement will determine the bone mineral density (BMD) for the area measured. This information will then be compared to the expected normal BMD range of adults according to your sex and race. The results will help your doctor determine if you need to take certain steps to protect your bone health. Bone density measurement is simple, noninvasive, painless, and quick (about 15 minutes in which you will be asked to remain very still).

You will be exposed to very little radiation — less than a standard chest x-ray. As with any medical procedure be sure to tell your doctor if you are pregnant.

Wear comfortable clothing, preferably something without metal buttons, buckles or zippers.
