What is the primary purpose of bone densitometry?

• A. To measure blood pressure
• B. To assess the risk of osteoporosis and fractures
• C. To analyze bone structure and composition
• D. To evaluate joint mobility

Answer: (B)

Bone densitometry primarily serves to assess the risk of osteoporosis and fractures. This technique involves measuring bone mineral density (BMD), which is crucial for determining bone strength and health. A lower BMD indicates a higher risk for osteoporosis, a condition characterized by weak and fragile bones that can lead to an increased likelihood of fractures.

By identifying individuals with low bone density, healthcare providers can implement preventative measures or treatment plans to reduce the risk of osteoporosis-related injuries, particularly in populations at greater risk, such as postmenopausal women and older adults. Understanding one's bone density is vital in managing bone health and preventing potential complications associated with osteoporotic fractures.
