What benefit does Dual-energy X-ray Absorptiometry (DXA) offer over previous technologies?

• A. Ability to measure multiple locations simultaneously
• B. Reduced scan time
• C. Comprehensive hormonal feedback
• D. Non-invasive sample collection

Answer: (B)

Dual-energy X-ray Absorptiometry (DXA) is a significant advancement in bone densitometry due to its reduced scan time compared to previous technologies. This efficiency is beneficial for both patients and healthcare providers as it minimizes the time a patient must remain still, which can enhance comfort and improve the overall experience of the procedure. A shorter scanning duration also allows healthcare facilities to process more patients in a given period, thus increasing throughput and optimizing resources. Additionally, DXA utilizes two different energy levels of X-rays to differentiate between bone and soft tissue, allowing for a precise measurement of bone mineral density (BMD) without requiring lengthy exposure times. This is particularly important in clinical settings where time is valuable and patient turnover needs to be managed effectively. While there are other advancements related to DXA, such as the ability to measure multiple sites in more advanced machines, reduced scan time remains one of its most critical benefits that enhance clinical efficiency. The other options might relate to features of different technologies or may not fully capture the principal advantage DXA brings to the practice of bone density scanning.
