Which imaging modality is commonly used to identify asymptomatic vertebral fractures in osteoporosis?

• A. Vertebral Fracture Assessment (VFA)
• B. Standard hip X-ray
• C. Abdominal ultrasound
• D. CT angiography

Answer: (A)

Vertebral Fracture Assessment uses the DXA scanner to obtain a lateral view of the thoracic and lumbar spine, specifically to detect compression deformities that may be present without symptoms. This method is ideal in osteoporosis evaluation because it can be added to a standard bone density test, delivering very low radiation, a quick exam, and the ability to uncover vertebral fractures that patients may not notice. Finding these fractures is important because they signal a higher risk of future fractures and influence treatment decisions, such as starting or intensifying osteoporosis therapy.

The other options don’t fit as well for this purpose. A standard hip X-ray focuses on the hip and isn’t practical for routinely screening the spine. Abdominal ultrasound doesn’t image vertebral bone structure. CT angiography is aimed at blood vessels and involves higher radiation and cost, not used for routine detection of asymptomatic vertebral fractures in osteoporosis.
