Abstract

The technical part of these Guidelines and Recommendations, produced under the auspices of EFSUMB, provides an introduction to the physical principles and technology on which all forms of current commercially available ultrasound elastography are based. A difference in shear modulus is the common underlying physical mechanism that provides tissue contrast in all elastograms. The relationship between the alternative technologies is considered in terms of the method used to take advantage of this. The practical advantages and disadvantages associated with each of the techniques are described, and guidance is provided on optimisation of scanning technique, image display, image interpretation and some of the known image artefacts.

Zusammenfassung

Der technische Teil dieser Leitlinien und Empfehlungen, der unter der Federführung der EFSUMB entstanden ist, enthält eine Einleitung zu allen physikalischen Grundlagen und Methoden der aktuell kommerziell erhältlichen Ultraschall-Elastografie-Technologien. Unterschiede in der Schersteifigkeit sind der wesentliche physikalische Mechanismus, dem der Gewebekontrast in allen Elastogrammen zu Grunde liegt. Die Beziehung zu alternativen Technologien wird und die Vorteile der angewandten Methode herausgearbeitet. Die praktischen Vorteile und Nachteile jeder Technik werden beschrieben und Empfehlungen zur Optimierung der Scantechnik, der Bildqualität und der Bildinterpretation gegeben, ebenso werden einige der bekannten Artefakte dargestellt.

Key words
