Which of the following is an advantage of quantitative ultrasound (QUS)?

• A. Requires specialized lab equipment
• B. Exposes patients to ionizing radiation
• C. Is expensive to perform
• D. Is portable and inexpensive

Answer: (D)

Quantitative ultrasound (QUS) is often favored for its portability and cost-effectiveness, making it accessible for a broader population and easier to use in various clinical settings. Unlike traditional imaging modalities that require extensive equipment and may be restricted to specific facilities, QUS can be performed in more diverse locations, including outpatient clinics or even in home health settings. This flexibility allows healthcare providers to assess bone density in patients who might have difficulty accessing conventional densitometry testing.

Additionally, the lower cost associated with QUS compared to other bone density testing methods supports wider screening initiatives and helps ensure that more patients can benefit from bone health assessments without significant financial barriers. The advantages of being portable and inexpensive foster greater adherence to screening recommendations, which is crucial in preventing osteoporotic fractures and managing bone health.
