Hologic Discovery Wi
Discovery Wi is a specific Discovery QDR DXA densitometer. Its manual includes spine, hips, forearm and whole-body scanning; additional applications may be optional. Check the location’s service description for fat and lean-tissue analysis.
Documented locations are available in Czechia.
What the results tell you
The manual documents spine, hip, forearm and whole-body scanning for Discovery Wi. The Wi suffix therefore identifies more than the general Discovery name. It still does not establish that every location offers composition analysis or the same software package. Tracking fat and lean tissue requires an actual whole-body service and analysis; bone-density examinations use the relevant region specified for the clinical purpose.
How the test works
During DXA you lie on a scanning table while the system uses X-rays at two energies. The operator selects position and scan scope for the booked examination. Spine or hip protocols differ from whole-body scanning. Composition software distinguishes fat, lean soft tissue and bone mineral, rather than separately weighing muscle or testing its function.
When the test is useful
Bone densitometry addresses mineral density at examined skeletal sites. Whole-body composition instead supports assessment of fat and lean-tissue distribution. Choose the service according to that goal. Trends benefit from the same system, protocol and analysis; results across manufacturers are not automatically comparable. A professional should interpret findings in relation to the examination’s purpose.
Preparing for your visit
Before booking, disclose possible pregnancy and recent contrast examinations so the location can assess suitability and timing. Follow instructions for clothing and metal objects. For repeat composition testing, keep meals, time of day, activity and bladder-emptying conditions similar. Check the actual table’s size and weight limits if relevant.
Reading results and understanding limitations
DXA body-composition testing is contraindicated in pregnancy. Contrast agents, artifacts, positioning and scan boundaries can affect results. Lean soft tissue is not pure muscle and does not express strength. Small changes must be assessed against the location’s measurement precision. A densitometer’s presence does not establish whole-body services or every optional application.
Choosing a testing location
Confirm the analysis actually offered rather than whole-body scan capability alone. Follow-up requires consistency in system, protocol and analysis.

Frequently asked questions
Does whole-body scanning capability on Wi mean the clinic offers it?
Confirm the analysis actually offered rather than whole-body scan capability alone. Follow-up requires consistency in system, protocol and analysis.
Does DXA directly measure muscle strength?
No. Lean soft tissue describes composition rather than strength or performance; muscle function requires an appropriate functional test.
