Bone mineral densitometry is a low energy X-ray that measures the level of minerals in your child’s bones. Learn about how this test is done.

Key points

  • BMD is a low-energy X-ray to measure the amount of mineral in your child's bones. It takes 15 to 30 minutes.
  • If your child has taken X-ray dye for another scan, they must wait before having the BMD.
  • If your child has a number of scans on the same day, the BMD must be done first.
  • A nuclear medicine doctor will send the results of the scan to your family doctor or paediatrician (child's doctor) within two working days. The person who does the scan cannot give the results.
