Bone Densitometry (Three Sites)

DEXA stands for Dual-Emission X-ray Absorptiometry. It measures how much calcium and other bone minerals are packed into a segment of bone.Two X-ray beams with differing energy levels are aimed at the patient's bones. Bone Marrow Density(BMD) is calculated from the absorption of each beam by the bone.DEXA can determine if you have osteoporosis or are at risk of osteoporosis and thus helps in assessing the risk of fracture.
