Article Synopsis
- The introduction of dual-energy X-ray absorptiometry (DXA) in the 1980s transformed how osteoporosis is diagnosed and managed globally.
- DXA results can be impacted by various technical factors, including instrument quality, patient positioning, and the interpretation of T-scores and Z-scores.
- This report aims to highlight important technical and clinical elements of DXA use and discusses how to better integrate these practices into clinical settings, along with considering non-bone mineral density measurements.
While analyzing dual-energy X-ray absorptiometry (DXA) examinations, we observed that, on occasion, the Ward region of interest (ROI) was positioned either unexpectedly or differently between successive examinations. When this occurred, it appeared to be either a marker of a compromised examination or of incident disease. This prompted a systematic inquiry.
