What is the main purpose of bone densitometry?

• A. To measure muscle mass
• B. To assess bone mineral density
• C. To evaluate joint health
• D. To analyze blood conditions

Answer: (B)

The primary goal of bone densitometry is to assess bone mineral density (BMD). This diagnostic procedure uses low-dose X-rays to quantify the amount of mineral content in bones, particularly at critical areas such as the spine, hip, and forearm. Assessing BMD is vital for diagnosing conditions such as osteoporosis or osteopenia, which indicate lower than normal bone density and increase the risk for fractures and other skeletal issues.

Bone densitometry plays a crucial role in evaluating the strength and health of bones, allowing healthcare providers to identify individuals at risk for bone-related diseases before serious complications arise. By focusing on bone mineral density, clinicians can make informed decisions regarding treatment interventions, lifestyle modifications, or follow-up screenings necessary to maintain or improve bone health.
