What scanning technology is most commonly associated with GE/Lunar and Norland systems?

• A. Computed tomography
• B. Magnetic resonance imaging
• C. K-Edge filtration
• D. Dual energy x-ray absorptiometry

Answer: (D)

Dual energy x-ray absorptiometry, often abbreviated as DXA or DEXA, is the scanning technology predominantly associated with GE/Lunar and Norland systems. This technology is specifically designed for measuring bone mineral density (BMD), which is crucial for diagnosing conditions such as osteoporosis.

DXA works by utilizing two different energy levels of X-rays to differentiate between bone and soft tissue, providing a precise measurement of bone density. By employing this method, practitioners can accurately assess an individual's bone health, which is essential for preventing fractures and managing osteoporosis.

The emphasis on DXA within the context of these systems stems from its widespread acceptance and effectiveness as a standard for bone density assessment in clinical practice. Clinics and medical facilities rely on DXA for its accuracy, low radiation dose, and ability to quickly provide results, making it a preferred choice for both practitioners and patients.
