Hologic Discovery QDR vs Hologic Horizon
Hologic Discovery QDR and Hologic Horizon: 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: when to consider it
Horizon is a family of DXA systems for bone densitometry. Selected configurations with body-composition software report fat, lean and bone components. A designation without a model letter does not establish which applications a location has available.

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.
