Bone Densitometry (DXA)
Other means of assessing bone strength are also available, but DXA is currently the most accurate method and uses the lowest amount of radiation for a pediatric bone scan.
In children, DXA is most often performed on the spine, hips or the entire body. It is a painless, non-invasive procedure – there are no injections or medications involved.
Your child’s doctor may order a DXA scan if your child:
- Has a recurrent or low trauma fracture.
- Has chronic inflammatory disease.
- Has hypogonadism.
- Is immobilized.
- Has a blood disorder.
- Is on long-term systemic glucocorticoid therapy.
- Has osteogenesis imperfecta.
The test may also be used to monitor treatment.
To reduce the possibility of a blurred image, your child must hold very still for a few minutes while the X-ray picture is taken. The test lasts 15 minutes.
