Zusammenfassung

Die Magnetresonanztomographie ist eine ausgezeichnete nichtinvasive Methode fürdie Beurteilung des morphologischen Status des Gelenkknorpels und des Knorpelersatzgewebes nach knorpelchirurgischen Eingriffen. Die am häufigsten für die Knorpeldarstellung verwendeten MRT-Tech-niken sind die Fast-spin-Echo-Sequenz und die dreidimensionale, fettunterdrückte Gradientenechosequenz. Neue MR-Techniken erlauben hochauflösende morphologische Untersuchungen undliefern weitere Informationen überdie Integrität von Knorpelersatzgewebe.

Summary

Magnetic resonance imaging is a useful non-invasive tool for the evaluation of the morphologic status of the native cartilage and cartilage repair after surgical procedures. With the introduction of fat-suppressed gradient-echo and fast spin-echo (FSE) sequences in clinical routine MR vis-ualization of the hyaline articular cartilage is routinely possible. While 3D gradient-echo with fat suppression allows exact depiction of the thickness and surface of cartilage, FSE outlines the normal and abnormal internal structures of the hyaline cartilage.
