Dual-Energy X-ray Absorptiometry (Discovery)

Manufacturer: Hologic

Model: Discovery 

The DXA is the gold standard clinical instrument used to evaluate body composition and bone mineral density. The analysis compares your values to a large database of healthy individuals to provide you two “scores”—the T-score and the Z-score.

WHAT DOES A DXA SCAN TELL US?

The T-score compares your results with healthy young adults and the Z-score compares your results with individuals of the same age and sex. The DXA is also a powerful clinical instrument used to diagnose osteoporosis.

The Advanced Body Composition assessment feature produces colour images displaying the distribution of fat, lean mass, bone and fat mass index. The information is translated into an easy-to-interpret report for improved patient management and counseling.

Is it possible to book the DXA for a research project? 

Yes, staff at the Centre for Hip Health and Mobility would be happy to address any questions you may have, discuss potential applications for the DXA, and work with you to coordinate your project.

Please contact us at equipment@hiphealth.ca.

Who can use the DXA?

Local, national, or international Researchers from:

  • Academic institutions
  • Industry
  • Government

The primary use of the DXA is for health research, however researchers in other fields are welcome to submit a project proposal.

We use the DXA

  • to assess hip and spine bone mineral content and density.
  • to evaluate total body, bone, fat and muscle mass.

Our Mobile Research Lab is equipped with advanced medical imaging technology including a Dual-Energy X-ray Absorptiometry (DXA), and a high level satellite communications systems to ensure secure and rapid data transfer of scan results.
