What is DEXA?

Updated: Nov 8, 2018

DEXA stands for dual-energy x-ray absorptiometry.

A DEXA scanner is an x-ray machine which was originally designed to assess bone health.

Bone is one of the components of your body weight. Doctors have been using DEXA as a valuable and accurate tool to assess bone health and diagnose bone diseases like osteoporosis for many years.

But more recently, DEXA has evolved to also measure the other components of your body weight (lean soft tissue and fat) and is now widely considered the most accurate way of assessing full body composition.

A DEXA with us at Physique Science can identify changes in body fat and muscle mass of as little as 200-300g. This is much more accurate than underwater weighing, Bodpod, bioelectrical impedance and skinfold (calipers) measurements where errors in excess of 1-2kg can be common.

DEXA consult with us is more than just a DEXA scan

With us, you get more than just a DEXA scan – you get a consultation with an accredited practicing dietitian who is experienced and qualified to answer your questions and offer responsible health advice.

We’re also happy to talk to your PT/dietitian/doctor… or if you don’t have a team yet, we can suggest the right services to help you achieve your goals. You won’t always have access to this sort of experience when you book for a DEXA scan, so don’t be afraid to ask the person who does your scan what their experience and qualifications are.

Because we want to help you learn as much as you can about your body and your health from your scan, your first appointment with us will be 30-minutes. We’ll take about 10 minutes to perform the scan and the rest of the time we’ll spend explaining your scan results with plenty of time to run through all the info you get from your report and answer all your questions.

Got questions? Drop us an email at

But most importantly… book your scan NOW and find out your DEXA health.
