KEY Clinical Aplikacje

Osteoporozys Screening andDiagnosis

Te mosty ustanawiają klinikal application of ultrasoncoc bone assessment is in thee screening and diagnosis of osteoporosis. Large prospectiva studies, such as thee EPIDOS and SOF trials, have demonstranted that QUS parameters - SOS, BUA, and stigness index - previd hip, converbbral, and non- converbral fractures incordimently of BMD. This means that a patient with normal BMD but poour QUS values may still be elevated fracture risk, and vice vale.

In practice, QUS is often used as a first-line screenting tool. Patients found to to bo at high risk based on QUS can then be referred for central DXA for confirmation and therament initiation. This two-step approvach maximizes resource efficiency while maintaing diagnostic cauxicacy.

Ocena ryzyka w ramach Fractury

Fracture risk is determinad d by bone density density bone quality. Ultrasonic testing captures elements of quality that density alone does not. For example, the trabecular structure plays a critical role in energy absorption during impact. BUA reflects this structure directly.
