Dexa scan is used to measure

• A. Bone Density
• B. Bone Mass
• C. Bone Shape
• D. Bone Lesion Size

Answer: (A)

DEXA scans measure bone density, specifically bone mineral density, by using two X-ray beams at different energies to estimate mineral content per unit area of bone. The result is given as a density value (g/cm2) and is interpreted with T-scores and Z-scores to assess osteoporosis risk and treatment response. This focuses on how much mineral is present in the bone, which relates to strength and fracture risk. It does not directly measure total bone mass, the external shape of the bone, or the size of bone lesions—these are evaluated with other imaging methods.
