DXA Scan

What is a DXA Scan?

A DXA scan stands for Dual-energy X-ray Absorptiometry. It’s a kind of scan that lets us safely and accurately measure how much bone, fat, and muscle a person has. In this study, we use it to learn more about how babies grow and develop.

Is it safe for babies?

Yes. The DXA scan uses very low levels of X-ray, much less than a standard chest X-ray. It’s safe for babies and commonly used in research like ours. The scan itself is quick, painless, and non-invasive—nothing touches or hurts your baby.

What happens during the scan?

• Your baby will be gently placed on a soft, open bed under the scanner.
• The scanner arm moves slowly over your baby’s body—it doesn’t touch them at all.
• A trained technician will be there the whole time to make sure your baby is comfortable and still.
• The scan takes about 7 minutes, and many babies sleep through it!
