Hologic Discovery QDR vs Hologic Horizon A

Hologic Discovery QDR and Hologic Horizon A: compare documented specifications, features and limitations. Check the reports and explanation offered by the provider. More features alone do not establish better accuracy.

Hologic Discovery QDR: when to consider it

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.

Hologic Horizon A: when to consider it

Horizon A is a specific Horizon DXA model with 216 detectors. Its documentation covers regional bone examinations and whole-body analysis. DXA lean soft tissue is distinct from a direct muscle-strength measurement.

Fat-free mass is not pure muscle mass. A single result is not a diagnosis. Different devices and similarly named metrics may use definitions that are not interchangeable.
