Quality assessment in bone densitometry: a case of incorrect hip analysis.

Dual-energy X-ray absorptiometry (DXA) is a sophisticated imaging technique utilized in the field of medical diagnostics to measure bone mineral density. The significance of DXA lies in its ability to accurately assess bone health, which is crucial in the evaluation of osteoporosis, a condition characterized by weakened bones and heightened susceptibility to fractures. Despite its widespread adoption and clinical utility, DXA is not without limitations. Factors such as body size, tissue hydration, the presence of metal implants, improper equipment installation and maintenance, as well as inadequate education and training in bone densitometry may influence DXA measurements, necessitating careful interpretation by trained professionals. We present a case to show the errors that occurred during DXA analysis leading to dramatic T-score changes, highlighting the importance of technologists' adherence to manufacturers' recommendations, to ensure the accurate processing of DXA scans and diagnosis.
