DXA stands for which imaging technique?

• A. Dual-energy X-ray Absorptiometry (DXA)
• B. Digital X-ray Analysis
• C. Dense X-ray Assessment
• D. Dual-energy Angiography

Answer: (A)

This question tests your knowledge of what the acronym DXA stands for in imaging. The imaging technique is Dual-energy X-ray Absorptiometry. It uses two different X-ray energy levels to distinguish bone from soft tissue and to quantify bone mineral density. This dual-energy approach lets the device calculate how much mineral is present in a given area, usually reported as areal bone mineral density in g/cm^2. It’s commonly used for osteoporosis screening and monitoring treatment because it provides a precise, low-radiation measure of bone strength at sites like the hip and spine. The other terms aren’t standard names for this technique—digital X-ray analysis, dense X-ray assessment, or dual-energy angiography refer to other concepts (general imaging, nonstandard terms, or imaging vessels with contrast) rather than bone density measurement.
