What does the DXA scan primarily evaluate?

• A. Bone geometry
• B. Fat distribution
• C. Bone density
• D. Cartilage thickness

Answer: (C)

The DXA scan, or Dual-energy X-ray Absorptiometry, primarily evaluates bone density. This imaging technique uses two different X-ray beams to measure the amount of mineral content in bones, specifically focusing on areas most affected by osteoporosis, such as the lumbar spine and hip. By quantifying bone mass and density, DXA scans help in assessing the risk of fractures and diagnosing conditions like osteoporosis or osteopenia. High-quality measurements provided by DXA scans are essential for monitoring bone health, tracking changes over time, and guiding treatment options for individuals at risk of bone density-related issues.
