DEXA Scans at Phoenix Children's Hospital

DEXA Scans at Phoenix Children's HospitalAt Phoenix Children's, we embace a concept of "Image Gently" which is our commitment to “kid-size” all of our techniques on a daily basis in order to dramatically reduce radiation doses during our exams.

What is a pediatric DEXA Scan?

DEXA is an abbreviation for "Dual Energy X-ray Absorptiometry". This is a special x-ray procedure that determines the strength of bones. Bone strength is assessed by measuring the bone density so a DEXA scanner is sometimes called a "bone densitometer."

DEXA is most often performed on the lower spine and hips. In children, sometimes the whole body is scanned. Peripheral devices that use x-ray screen for a bone deficiency or bone loss in your child.

Getting a DEXA scan is a painless, non-invasive procedure:

  • There are no injections or medications involved.
  • The procedure takes place in a private, child-friendly room.
  • DXA is an open machine - patients are not enclosed at any time.

What happens during an DEXA Scan?

In the Central DXA examination, which measures bone density in the hip and spine, your child would lie on a padded table. An x-ray generator is located below the patient and an imaging device is positioned above.

To assess the spine, the child's legs are supported on a padded box to flatten the pelvis and lower (lumbar) spine. To assess the hip, the patient's foot is placed in a brace that rotates the hip inward. In both cases, the detector is slowly passed over the area, generating images on a computer monitor

Your child must hold very still for a few minutes while the x-ray picture is taken to reduce the possibility of a blurred image.

These tests take approximately 10 to 30 minutes.
