Zusammenfassung
Verfahren des quantitativen Ultraschalls (QUS) sind geeignet, Aussagen über die Bruchempfindlichkeit des Skeletts zu treffen. So existieren umfangreiche Studienergebnisse über die Eignung von QUS für die Abschätzung des osteoporotischen Frakturrisikos. Allerdings muss dabei der Vielfalt unterschiedlicher Technologien, Geräte und Messvariablen sowie dem unterschiedlichen Validierungsgrad einzelner Geräte Rechnung getragen werden.
Mit Methoden zur Simulation der Ausbreitung von Ultraschallwellen konnte die komplexe Wechselwirkung zwischen Ultraschall und Knochen besser verstanden und die Schallausbreitung visualisiert werden. Vor einem weiten klinischen Einsatz ist noch zu klären, ob auch Patienten mit niedrigen QUS-Werten von einer Therapie profitieren, so wie es für die 2-Energien-Röntgenabsorptiometrie (DXA) gezeigt werden konnte. Weiterhin ist die Einführung von Qualitätssicherungsmaßnahmen notwendig. Auch sollte der Anwender die Grenzen der Verfahren kennen und die Ergebnisse korrekt interpretieren können. Richtig eingesetzt, könnten QUS-Verfahren aufgrund niedrigerer Kosten und des Fehlens ionisierender Strahlung eine bedeutende Rolle im Osteoporosemanagement spielen.
Abstract
Methods of quantitative ultrasound (QUS) can be used to obtain knowledge about bone fragility. Comprehensive study results exist showing the power of QUS for the estimation of osteoporotic fracture risk. Nevertheless, the variety of technologies, devices, and variables as well as different degrees of validation of the single devices have to be taken into account.
Using methods to simulate ultrasound propagation, the complex interaction between ultrasound and bone could be understood and the propagation could be visualized. Preceding widespread clinical use, it has to be clarified if patients with low QUS values will profit from therapy, as it has been shown for DXA. Moreover, the introduction of quality assurance measures is essential. The user should know the limitations of the methods and be able to interpret the results correctly. Applied in an adequate manner QUS methods could then, due to lower costs and absence of ionizing radiation, become important players in osteoporosis management.
