Magnetresonanztomographie des Gelenkknorpels

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.
