DEXA / BMD

Everything you need to know about DEXA/BMD

How DEXA/BMD scans work

Bone mineral densitometry (BMD) scans use a small dose of radiation to measure the density of bones. During the scan, patients lie on their back on a wide, flat bed. A camera arm will pass over the top of them taking a series of images.

DEXA/BMD can be used to examine most parts of the body, including:

What to expect

A DEXA/BMD scan is quick and non-invasive.

Upon arrival, you may be asked to change into a gown. You’ll be taken into the BMD scanner room and asked to lie flat on the scanning bed. A scan is routinely performed of your hips, lower spine, and sometimes your forearm. Each area takes approximately 5 minutes and you’ll need to remain still during the scan.

Patient stories

The radiation exposure of a BMD is less than 10% of a standard chest x-ray.

FAQs

No. It’s sufficient to determine bone density from the snapshots of your hip/s, lower spine, and sometimes forearm. There’s no need to expose the rest of your body to x-rays as it doesn’t provide any additional information.
BMD is the most effective scan for determining bone density loss and confirmation of Osteoporosis. Osteoporosis doesn’t have any symptoms and it’s important to diagnose early to prevent further bone density loss or osteoporotic fracture. Your doctor may request a BMD scan if you have:
  • A recent fracture from a minor injury
  • Had an X-ray or CT showing that the bones in your spine are weakened
  • A medical condition that could cause bone density loss
  • Regular medication that could cause bone density loss
A medical imaging technologist who is skilled in performing BMD scans. They’ll ensure that you’re comfortable during your scan and position each area to achieve a quality and repeatable image.
The results from each separate image will be compared to a normal bone density range for your age and gender. A specialist will review your results and images and provide a report to your referring doctor.
