What does DXA radiology equipment measure?

• A. Bone density and fracture risk
• B. Velocity and reduction of density
• C. Whole body fat percentage
• D. Joint space narrowing

Answer: (A)

DXA (Dual-energy X-ray Absorptiometry) radiology equipment is primarily designed to measure bone density, which is a critical factor in assessing bone health and determining fracture risk. This technique uses low-dose X-rays at two different energy levels to distinguish between bone and soft tissue, allowing for accurate quantification of bone mineral density (BMD). The measurements obtained from DXA scans are essential for diagnosing conditions such as osteoporosis, where low bone density leads to an increased risk of fractures. By assessing bone density, clinicians can make informed decisions about treatment options, such as the need for medications or lifestyle changes to improve bone health, thereby directly correlating bone density to fracture risk assessment. Other options, such as measuring velocity and reduction of density, whole body fat percentage, or joint space narrowing, are not the primary focus or capability of DXA technology, which solidifies option A as the most accurate response regarding what DXA radiology equipment measures.
