What is the primary purpose of Vertebral Fracture Assessment (VFA)?

• A. To evaluate bone density
• B. To diagnose vertebral fractures
• C. To measure T-scores
• D. To assess overall bone health

Answer: (B)

The primary purpose of Vertebral Fracture Assessment (VFA) is to diagnose vertebral fractures. This imaging technique specifically focuses on identifying the presence of vertebral compression fractures using low-dose dual-energy x-ray absorptiometry (DXA) images. VFA provides valuable information about the structural integrity of the spine, which is critical in patients at risk for osteoporosis and related fractures.

By pinpointing where fractures may have occurred, healthcare providers can assess the severity and implications of these fractures in conjunction with overall fracture risk. This is particularly important for managing and treating individuals with osteoporosis, as vertebral fractures are common and can lead to significant morbidity. Thus, VFA plays a crucial role in determining not only the presence of fractures but also in guiding treatment decisions to reduce future fracture risk.
