Bone scanner showdown: are new machines as accurate as the old?
NCT ID NCT02609191
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested two different bone densitometers (the Stratos DR and the Discovery A) to see if they give the same results when measuring body fat and lean muscle mass. Fifty adults who were already scheduled for a bone density scan took part. Each person was scanned on both machines, and some had repeat scans to check consistency. The goal was to see if the newer Stratos DR machine can be trusted for routine clinical use.
