Abstract

Bone mineral densitometry (BMD) using dual-energy X-ray absorptiometry (DXA) is widely recognized as the standardmethod for evaluating bone density. DXA produces attenuation maps that aid in measuring BMD. Non-relevant findingsare commonly observed in DXA images, some of which may influence BMD measurements, while others have limited clinicalsignificance. While opinions vary, the majority of studies suggest that vascular calcifications do not significantly affect BMD.We present a case of an 84-year-old female who presented for BMD evaluation emphasizing the need to consider differentconfounding factors in results interpretation.Keywords: Bone Mineral Density (BMD) overestimation, Dual-energy X-ray Absorptiometry (DXA), vascular calcifications
