Frequently Asked Questions

What is a DXA scan?

A dual-energy x-ray absorptiometry (DXA) scan is a test that takes measurements of the bone density in the lower spine and/or the hip. This information helps determine how strong your child's bones are. It may also include information on the amount of your child's body weight that is made of bone, muscle and fat. The DXA scan is a test doctors use to help prevent fractures. It also helps them monitor treatment for conditions that cause weakened bones.

Why does my child need to have a DXA?

Certain conditions and medications can decrease your child's bone health. Weaker bones are more likely to fracture. It is important to monitor bone density to help prevent problems.

How long does the test last?

It takes about 15 minutes.

Is there any radiation exposure?

The X-ray exposure is less than what you receive during a cross-country airplane trip or in two hours of sunshine.
