Hologic Discovery QDR
Hologic Discovery QDR: DXA testing
Discovery QDR is a family of DXA bone densitometers. The manual lists spine, hip and forearm testing across the series and whole-body scanning on A, W and Wi. A generic QDR Discovery designation does not establish whole-body analysis at a specific location.
Distinguish bone densitometry from body-composition analysis before booking. Check the scan type and report offered by the specific location.
A listing is neither manufacturer endorsement nor an accuracy rating.

How it measures
DXA (also called DEXA) uses X-rays at two energies. Bone densitometry using this method measures bone density, usually in the spine and hip. Body-composition assessment requires a whole-body analysis separating fat and lean soft tissue and bone mineral. A bone-density test alone does not establish that this service is available. Pregnancy is a contraindication to DXA body-composition testing.
Benefits
- Compare the documented model specifications before choosing a provider.
What the device does not tell you
- Check whether the provider offers body-composition analysis or only bone-density testing. These are different services.
Compare devices
For tracking change, ask about using the same device and procedure and having the results explained. For clinical examination, confirm referral and booking requirements with the provider. Differences between methods are not automatically changes in your body.
