NCT ID NCT06305156
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested how well a new type of CT scanner measures bone density compared to the standard DXA scan. 167 adults who already needed a CT scan also had a DXA scan. The goal was to see if the CT could accurately detect osteoporosis and how to make the scan even better.
