What does DXA radiology equipment measure?

The primary function of DXA (Dual-Energy X-ray Absorptiometry) radiology equipment is to measure bone density, which directly relates to fracture risk. DXA scans assess the mineral content of bones, providing quantitative data regarding bone mass and density. This information is crucial for diagnosing conditions such as osteoporosis, where low bone density significantly increases the risk of fractures.

While some DXA equipment can also provide whole body composition analysis, including fat percentage, that is not its primary purpose when specifically discussing the primary metrics it measures. Moreover, DXA does not measure velocity or reduction of density; rather, it captures static density values that can help predict changes over time through comparative studies.

Therefore, the measurement of bone density and fracture risk is the key aspect of DXA radiology equipment, making it integral in both clinical practice and research related to skeletal health.
