Which unit is used to express results from DXA scanning?

• A. g/cm squared
• B. cm/m squared
• C. mL/g
• D. kg/cm

Answer: (A)

The unit that is used to express results from DXA (Dual-energy X-ray Absorptiometry) scanning is grams per square centimeter (g/cm²). This unit of measurement is vital in bone densitometry, as it quantifies the bone mineral density (BMD) by indicating the mass of mineral content in grams per area of square centimeters for a specific region of the body, usually the lumbar spine, hip, or forearm. This measurement allows for the assessment of bone density and can help in diagnosing conditions such as osteoporosis or assess fracture risk. The use of g/cm² provides a clear and standardized way to report BMD values, facilitating comparisons across different studies and patient evaluations. It reflects not only the bone density but also gives insight into overall bone health, which is essential for clinicians in managing patient care effectively.
