What does the BUA stand for in bone densitometry?

• A. Bone Ultrasound Amplitude
• B. Bone Ultrasound Attenuation
• C. Bilateral Ultrasound Analysis
• D. Bone Ultrasound Assessment

Answer: (B)

Bone Ultrasound Attenuation, represented by the acronym BUA, is a measure used in bone densitometry that reflects how much ultrasound waves are reduced in intensity as they pass through bone. This attenuation is indicative of the bone's density and quality. A higher attenuation generally suggests denser and healthier bone, while lower levels can indicate a higher risk of osteoporosis or fractures. In bone densitometry, BUA is an important parameter because it helps in assessing bone health without the use of ionizing radiation, making ultrasound a safer alternative for certain patient populations, such as children or those who may need repeated monitoring. The information derived from BUA can aid clinicians in diagnosing conditions related to bone health and even in monitoring the effectiveness of treatment regimens over time.
