Quantitative ultrasonography (QUS) of the calcaneus is a low-cost portable screening tool. It has the advantage of not involving radiation, but it is not as accurate as other imaging methods. Ultrasonography cannot be used for monitoring skeletal changes over time, nor can it be used to monitor the response to treatment, because of its lack of precision.
