What does Quantitative Ultrasound (QUS) measure?

• A. BMD through X-rays
• B. Broadband attenuation properties of bone
• C. Bone density with sound waves
• D. Radiographic images of bone structure

Answer: (B)

Quantitative Ultrasound (QUS) is specifically designed to assess the properties of bone using ultrasound waves, and one of the primary measurements it provides is the broadband attenuation properties of bone. This refers to how much sound waves are absorbed and scattered by the bone, which can provide insight into the bone's quality and potential strength. Using this method, practitioners can evaluate the mechanical properties of bone, which are important for assessing fracture risk, particularly in populations at risk for osteoporosis. QUS does not measure bone mineral density (BMD) using X-rays or produce radiographic images, which distinguishes it from other methods such as dual-energy X-ray absorptiometry (DEXA). QUS is notable for being a non-invasive, quick, and cost-effective method for evaluating bone health compared to traditional X-ray techniques.
